Why it's listed

Three brick buildings on East Broadway in South Boston form this small district: a church flanked by two houses, set on one of the highest points of the neighborhood. The church was built for a Unitarian congregation between 1872 and 1873 and designed by local architect Samuel J.F. Thayer in a High Victorian Gothic style influenced by Venetian Gothic. Its T-shaped plan, lancet arches, sandstone trim and engaged tower solved the problem of a narrow lot hemmed in by neighboring buildings. Inside, the black walnut woodwork, balcony, parlors and Sunday School room survive largely intact, along with a Byzantine-style altar screen added when the building became the Cathedral of St. George. The two houses, at 517 and 525 East Broadway, were linked to prominent church members and builders, and a deed condition required that only brick or stone dwellings be built beside the church. Together they show how a church and its surrounding residences developed in South Boston during the 1870s.

What listing means for this property

This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
