One of the world's supreme ancient mysteries is also among its most obscure. In a remote corner of the western Pacific Ocean, nearly 1,000 miles north of New Guinea and 2,300 miles south of Japan, stand the massive ruins of a long dead city. Incongruously built on a coral reef only five feet above sea level between
the equator and the eleventh parallel, Nan Madol is a series of rectangular
islands and colossal towers choked by draping vegetation. During its prehistoric lifetime, sole access to Nan Madol was via the ocean, from which vessels entered an open-air corridor flanked by artificial islets. At the end of this sea-lane still remains the only entrance to the city, a dramatically impressive flight of broad stone steps rising to a plaza. Ninety-two artificial islands are enclosed within the "downtown" area's 1.6 square miles. All are interconnected by an extensive network of what appear to be canals, each twenty-seven feet across and more than four feet deep at high tide.
An estimated 250 million tons of prismatic basalt spread over 170 acres went into the construction of Nan Madol. Its stone girders rise in a Lincoln Log–like cribwork configuration to twenty-five feet. Originally, the walls rose higher still,
perhaps by another ten or twenty feet. Better estimates are impossible to
ascertain, because the Pacific metropolis is being slowly, inexorably dismantled by relentless jungle growth, which is dislodging the unmortared ramparts and scattering their roughly quarried blocks to the ground. David Hatcher Childress,who conducted several underwater investigations at Nan Madol in the 1980s and early 1990s, concludes that "the whole project is of such huge scale that it easily compares with the building of the Great Wall of China and the Great Pyramid of Egypt in sheer amounts of stone and labor used, and the gigantic scope of the site." In fact, some of the hewn or splintered basalt prisms built into Nan Madol are larger and heavier than the more than two million blocks of Khufu's
Pyramid. Between four and five million stone columns went into the
construction of the Caroline Islands' prehistoric metropolis.

Outcrops of basalt were quarried by splitting off massive splinters into the
quadrangular, pentagonal, or hexagonal "logs" that went into building Nan
Madol. They were hewn roughly into shape, then loosely fitted without benefit
of mortar or cement, in contrast to the finely lined and joined stonework found in
the supposed canals. These prismatic columns usually range in length from three
to twelve feet, although many reach twenty-five feet. Their average weight is
around five tons each, but the larger examples weigh twenty or twenty-five tons
apiece. According to Science magazine, "At places in the reef there were natural
breaks that served as entrances to the harbors. In these ship-canals there were a
number of islands, many of which were surrounded by a wall of stone five or six
feet high."
In fact, the entire site was formerly encircled by a sixteen-foot-high wall
originally 2,811 feet long. Only a few sections of this massive rampart have not
been broken down by unguessed centuries of battering storms, against which still
stand two breakwaters. One is 1,500 feet in extent, but the other, nearly three
times greater, is almost a mile long. Some of Nan Madol's walls are more than
twelve feet thick, to what purpose no one has been able to determine because
they are not part of any military fortifications. There is no evidence of keystones
or arches, just a simple slab lintel placed over doorways. None of the presumed
"houses" have windows; nor are there any streets, only what may be canals. Yet
the site did not result from haphazard episodes of construction over several generations. Its overall layout of structures deliberately grouped and positioned
into orderly sections attests to an organized plan carried out with single-minded
purpose in a relatively short time.
The city's best-preserved building is known as Nan Dowas, a tall, square,
hollow, windowless tower composed of fifteen-foot-long hexagonal black basalt
pillars laid horizontally between courses of rudely cut boulders and smaller
stones. The islet is a double-walled enclosure comprising 13,500 cubic meters of
coral, with an additional 4,500 cubic meters of basalt. Although the site
comprises numerous other structures, they are dominated by Nan Dowas.
Childress points out that "the entire massive structure was built by stacking
stones in the manner in which one might construct a log cabin." The
southeastern side of Nan Dowas features the city's largest block, a single
cornerstone weighing no less than sixty tons. Digging underneath this impressive
megalith, archaeologists were surprised to discover that it had been intentionally
set on a buried stone platform.
They were in for yet another surprise when they found a large tunnel cut
through coral running from the center of Nan Dowas. An entire network of
underground corridors connecting all the major man-made islands was
subsequently revealed, including an islet known as Darong joined by a long
tunnel to the outer reef that surrounds the city. Incredibly, some tunnels appear
to run beneath the reef itself, exiting into caves under the sea. Darong is also
notable for its stone-lined artificial lake, one of several found throughout the
complex. What appears to be its longest tunnel extends from the city center out
into the sea for perhaps half a mile. Larger even than Nan Dowas is the artificial
islet of Pahnwi, containing 20,000 cubic meters of coral and basalt rock.
Estimates of the 20,000 to 50,000 workers needed to build Nan Madol are in
sharp contrast with the native population of Pohnpei. This inhabited island just
offshore could never have supported such numbers.
But not a single carving, relief, petroglyph, or decoration of any kind has
been found at Nan Madol, nor any idols or ritual objects—in fact, few artifacts at
all to identify its builders. No statues or sculpture ever adorned its watery
boulevards. Not even one of the small, portable stone images commonly found
throughout the rest of Micronesia and across central and western Polynesia was
discovered at the site. Nor has a single tool or weapon so far been recovered.
Although a ruin, the city is not difficult to envision during its heyday.
Remove all concealing vegetation, and visitors would behold crudely worked
masses of basalt contrasting with orderly courses of stone rising in massive
towers and overpowering walls amid a complex of smaller rectangular buildings
and artificial lakes interconnected by dozens of canals, spread out over eleven
square miles. No wonder Nan Madol has been referred to as the Venice of the
Pacific. But it had no marketplace, temples, or storage areas, not even a
cemetery to bury its dead.
The name Nan Madol means "spaces between," referring to the spaces
created by the network of canals, while Pohnpei (Ponape, until its incorporation
in the Federated States of Micronesia, in 1991), means "on an altar." Its ruins are
not confined to the coral reef facing Madolenihmw Harbor, but may be found
across Pohnpei itself and on several offshore islands. A rectangular enclosure
forty-six feet long by thirty-three feet wide, with a bisecting three-foot-high
interior wall, was discovered in a remote, swampy meadow high in the
mountains, near Salapwuk. Although the twin courtyards enclose a 1,520-
squarefoot area, a pair of inner platforms are only one foot high. As at Nan
Madol, roughly cut basalt boulders and basalt logs were stacked to form the
enclosure. Several others stand on Pohnpei's southwest coast, with the largest example atop a 720-foot mountain. The summit is surrounded by walls five and
seven feet high connected by paved walkways to several terraced platforms.
About a quarter of a mile away, to the southwest, several so-called crypts
were found at Pohnpei, but no trace of human remains have ever been recovered
from the 12.5-to 14.8-foot-long containers, whose real function has not been
identified. Nearer the coast, Diadi features a finely made basalt enclosure with a
platform 1,060 feet square. Alauso's two-tiered, 340-foot-square pyramid with a
central fire pit stands not far from the sea, near Kiti Rock's 24-foot-square
platform, with four upright basalt columns at each of the inner corners. Sokehs
Island, separated from Pohnpei by a mangrove swamp, is crossed by numerous
stone pathways connecting platforms.
Significantly contributing to the mystery of these structures, it would be
difficult to imagine a more out-of-the-way place than Pohnpei, a mere speck
amid the 4.5 million square miles of western Pacific Ocean surrounding
Micronesia. Sea-lanes and trading routes are thousands of miles away. As the
encyclopedist of ancient anomalies William R. Corliss observes, "Only one
hundred twenty nine square miles in area, it is almost lost in the immensity of
the Pacific."
Totolom, Tolocome, or Nahnalaud, the "Big Mountain," rises 2,595 feet
from the middle of the squarish, twelve-by-fourteen-and-a-half-mile island,
overgrown with mangrove swamps but devoid of beaches. Pohnpei is just
thirteen miles across and is surrounded by a coral reef, together with twenty-
three smaller islands. Abundant rainfall—195 to 200 inches annually—conjures
a profusion of ferns, orchids, creepers, bougainvillea, and hibiscus throughout
thickly wooded valleys and across steep mountainsides. Humidity is excessive,
and mildew, rot, and decay permeate the island. Additionally, its remote location
hardly seems to qualify Pohnpei as an ideal spot to build a civilization. Indeed,
the island has nothing to offer for such a gargantuan undertaking as Nan Madol.
Yet its very existence implies city planning, a system of weights and
measures, division of labor, and a hierarchy of authority, plus advanced
surveying and construction techniques on the part of its builders. All this was
needed to raise the only premodern urban center in the entire Pacific. But what
kind of a place was it, this city without streets, windows, or art? Bill S.
Ballinger, whose Lost City of Stone was an early popular book on the subject,
observed, "Nothing quite like Nan Madol exists anywhere else on Earth. The ancient city's construction, architecture and location are unique."
At Pohnpei's northern end, Kolonia, its capital and the only town on the
island, stands in stark contrast to the magnificent achievement just across the
bay. Unlike the orderly precision evident at Nan Madol, Kolonia grew
haphazardly, with no regard to planning of any kind, and is today inhabited by
perhaps 2,000 residents who live in mostly one-story, cinder-block buildings
with corrugated tin roofs. In contrast to the prehistoric stone pathways that still
crisscross the island, some fifteen miles of dirt roads are often impassable,
especially during the frequent downpours. Many islanders dwell in small shacks
of dried grass, cane, and bamboo, not monumental stone. "Kolonia is anything
but beautiful," writes Georgia Hesse of the San Francisco Examiner, "a cluster
of weathering wood and rusting corrugated buildings strung anyhow along a
wide street." Employment opportunities are virtually nonexistent, so the natives
lead subsistence lives from the richly fertile, volcanic soil, their diet
supplemented by fish and chickens.
The Carolines have never supported a population growth commensurate with
the labor needed to build the Venice of the Pacific. As Ballinger put it, "The
point is that large reserves of manpower were never readily available in and
around Ponape. This is a factor that must always be considered when trying to
solve the mystery of the construction of Nan Madol." Pohnpei's 183 square
miles are mostly mountainous and uninhabitable, barely able to support its
30,000 inhabitants. Only a far greater number would have justified, let alone
been able to build, a public works project on the huge scale of Nan Madol. A
leading New Zealand scholar of the early twentieth century, John Macmillan
Brown, noted, "The rafting over the reef at high tide and the hauling up of these
immense blocks, most of them from five to twenty five tons weight, to such a
height as sixty feet must have meant tens of thousands of organized labor; and it
had to be housed and clothed and fed. Yet, within a radius of fifteen hundred
miles of its centre there are not more than fifty thousand people today." Just
about that many workers would have been needed to assemble Nan Madol's four
or five million basalt logs in approximately twenty years.
Today, Pohnpeians lay little claim to the archaeological site outsiders find so
awe-inspiring. Science magazine reports, "The natives have no tradition
touching the quarry, who hewed the stone, when it was done, or why the work
ceased." They mostly avoid the place as evil and dangerous, where visitors after
dark were known to have been killed by some mysterious power. Indeed, the
islanders appear to have always considered it taboo, at least into the late
nineteenth century. More than 100 years later, a few local guides are willing to escort outsiders to the site, but never after dark. According to Ballinger, "Present
Ponapeans and their preceding generations have demonstrated no skill, or even
interest, in any kind of stone construction. The building of the city demanded
considerable engineering knowledge," which the indigenous residents have
never demonstrated. "I had to use all my powers of persuasion even to find two
boys to take me over to Nan Madol every day," complained the famous "ancient
astronaut" theorist Erich von Daniken, when he visited Pohnpei in the early
1970s. Citing the thousands of work hours, complex organization, and well-
directed labor required to quarry, transport, and erect 250 million tons of basalt,
a U.S. Department of the Interior report stated, "The unwritten history of Ponape
indicates that Nan Madol was constructed by or under the direction of people not
native to the island of Ponape." Von Daniken dismissed the modern natives as
"poor and incurably lazy and [with] no interest in business." William Churchill,
an early-twentieth-century American ethnologist at Pohnpei, concluded that the
prehistoric city was "utterly beyond the present capacity of the islanders." He
echoed the sentiments of the ship's surgeon of the Lambton, a British cutter that
anchored at the island in 1836. Dr. Campbell concluded that Nan Madol was
"the work of a race of men far surpassing the present generation, over whose
memory many ages have rolled, and whose history oblivion has shaded forever,
whose greatness and whose power can only now be traced from the scattered
remains of the structures they have reared, which now wave with evergreens
over the ashes of their departed glory, leaving to posterity the pleasure of
speculation and conjecture."
To be sure, the islanders' own traditions suggest as much. They recount that
seventeen men and women who arrived from a land far to the south created
Pohnpei by piling rocks upon the local coral reef. This work accomplished, the
inhabitants—mixed offspring of natives and newcomers—descended from these
first inhabitants. Over time, their numbers multiplied, but they lived in perpetual
anarchy. Much later, riding in a "large canoe," the twin brothers Olisihpa and
Olsohpa arrived from a different homeland in the west, remembered as Katau
Peidi. When this Motherland, known by many different names to various Pacific
Islanders, was referred to as Kanamwayso, its myth depicted a splendid kingdom
from which a people of great power very long ago sailed throughout the Pacific.
Falling stars and earthquakes were responsible for setting Kanamwayso aflame
and dropping it to the bottom of the ocean, where it is still inhabited by the
spirits of those who perished in the cataclysm, who preside over the ghosts of all
those who die at sea.
Olisihpa and Olsohpa were sorcerers, wise and holy men, and very tall. They
first landed on the northern end of Pohnpei but found the geography there
somehow unsuited to their purposes. Three times more they tried to establish
themselves along the east coast—at the summit of Net Mountain,
Nankopworemen, and U, where the supposed remains of these failed attempts
are still pointed out by local guides.
But each location failed some predetermined requirement. At last, after a
careful search, the perfect site was found at Sounahleng, a reef at Temwen
Island, upon which Olisihpa and Olsohpa built Nan Madol with the aid of a
"flying dragon." After it cut through the coral, dredging the canals, the twin
sorcerers levitated the ponderous basalt logs through the air, piling them to a
great height, and fitted them neatly into place. The work took only a single day
to complete. Thereafter, Nan Madol became a sacred city and administrative
center, from which the brothers brought government and social order to Pohnpei.
They ruled together for many years, until Olisihpa died of old age, and Olsohpa
assumed sole power as the first Saudeleur, or lord of Deleur, an early name for
the island. He married a local woman, from whom he sired twelve generations of
Saudeleurs, who continued to rule wisely and peacefully until the arrival of the
ancestors of the modern Pohnpeians.
They were led by a warrior chief from the south, Isokelekel, who killed
Saudemwohl, the last of the Saudeleurs. His was an easy victory, because the
lords of Deleur never concerned themselves with military affairs. Isokelekel's
line endured through the centuries into the modern era, despite years of
occupation by foreign powers, until shortly before Pohnpei became first part and
then capital of the independent Federated States of Micronesia, in 1984. Samuel
Hadley was the last Nahnmwarki to assume the title, in 1986.
Something of this mythic version of Nan Madol's origins came to light
during 1928, when Japanese archaeologists excavated human skeletal remains
near several prehistoric sites on Pohnpei. While the bones numbered only a few
dozen pieces and were incomplete and in poor condition, enough survived to
show that they belonged to people unlike the indigenous islanders. Their ancient
predecessors were far taller and more robust. Discovery of these anomalous
skeletal fragments was supported by surviving evidence. The men of Pohnpei
still make and use a kind of throwing spear they claim as an inheritance from the
Saudeleurs of long ago. While Polynesians and other Micronesians traditionally
employ spears five to seven feet long, the Pohnpei spear is a unique twelve feet,
suggesting the tall descendants of Olisihpa and Olsohpa.Olisihpa and Olsohpa were sorcerers, wise and holy men, and very tall. They
