Chatham Square

Neighborhoods: Bluff, Central Business District

Chatham Square is named after William Pitt, 1st Earl of Chatham (1708–1778), who is also the eponym of Pittsburgh itself.[1, 2, 3, 4] See also Beechwood Boulevard, which was named William Pitt Boulevard from 1910 to 1913, and Stanwix Street, the northern part of which was originally named Pitt Street.

A short street between Bigelow Boulevard and Centre Avenue, immediately west of Interstate 579, is identified by a sign at the Centre Avenue intersection as Chatham Street.
