The original plan for the town contained 340 lots. Most of this area is now designated as a Historic District and in addition to regular government zoning and permitting, a historic review is required when a building is renovated or repaired. The object is to preserve the architectural and archeological heritage of the site. Last week I posted a photo of a 1756 house. These today were built in the late 1800's. Originally the buildings were residences, but now some are businesses. The architectural style of these houses was prevalent throughout other US cities during 1870 - 1900.
