Belfast Commercial Historic District, Belfast

The Belfast Commercial Historic District encompasses two blocks of the central business district of Belfast, Maine. This area includes the best-preserved and most architecturally interesting commercial buildings of the city's mid-to-late 19th century development, when it was the leading port on Penobscot Bay. It extends along Main Street from the major intersection and Church Street north to Washington Street. It was listed on the National Register of Historic Places in 1980, and is entirely contained within the larger Belfast Historic District. ()
