Why it's listed

Harvard Square in Cambridge, Massachusetts, is a dense mix of shops, student housing, clubs, churches and houses, and this boundary increase adds roughly 35 acres to the existing historic district. The buildings date from 1631 to 1941. The area grew from Cambridge's 1630 grid plan, and South and Winthrop Streets still keep their original 12-foot width, along with Winthrop Square, the old marketplace. Surviving Federal and Greek Revival houses, such as the Augustus Wyeth House of 1829, show the nineteenth-century neighborhood. Later growth is shown by the Fairfax block, expanded between 1869 and 1900, and by private dormitories and clubs built from the 1880s, including the Porcellian Club and the Harvard Lampoon Building. Georgian Revival and Art Deco commercial buildings from 1908 to 1941 reflect the subway era. Reviewers found the area well documented for its historical and architectural importance and accepted it under Criteria A and C.

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).
