The Market Square Historic District of Newburyport, Massachusetts encompasses an area of the city near the Merrimack River that was completely rebuilt after a major fire in 1811. Over the next twenty years the area was rebuilt under a building code requiring either brick construction or size limits on wood-frame buildings. As a consequence the Market Square area has a remarkable concentration of Federal style brick buildings. Among the most notable are the Custom House, now a museum, and the 1823 Market House, which forms the district's eastern boundary.[1] The district includes Market Square and properties fronting on State, Merrimac, Liberty, and Water Streets. It was listed on the National Register of Historic Places in 1971.
