Portsmouth Downtown Historic District
The Portsmouth Downtown Historic District encompasses the historic urban core of Portsmouth, New Hampshire. With a history dating to the 17th century, Portsmouth was New Hampshire's principal seaport and the center of its economy for many decades, and the architecture of its urban center is reflective of nearly four centuries of history. The district is roughly L-shaped, radiating from the downtown Market Square area to South Street in the south and Madison and Columbia streets in the west, with more than 1,200 historically significant buildings. It was listed on the National Register of Historic Places in 2017. The district includes 35 previous listings on the National Register, and five National Historic Landmarks. (read more...)
