The streets of Boston in Massachusetts were occupied with rows of houses built using the first period style of architecture. The buildings were in many ways almost closer to a medieval style building in England, with the tiny windows, steeply pitched roofs and a basic plank door. During that time ─ in 1633 glass was extremely expensive and hard to produce due to unimproved technology so the windows were small with tiny, diamond shaped panes. There was a house that was huge and there was a central chimney, and a long slanted roof sloping down to a shed at the back ─ this style was called a "Saltbox" as it looked like the box that held the salt.
