United States Post Office - Downtown 17 Conant St, Danvers, MA01923 Danvers didn't receive federal authorization for a U.S. Post Office branch until the 1930s, and this brick building just…More off Danvers Square on Conant Street was built and opened in April 1936. The postmaster at the time was James D. Sullivan. The mural in the lobby was painted in 1939, a product of the federal Work Projects Administration, and depicts former Postmaster General Timothy Pickering coming to town in 1802. These days, the last daily collection of mail is at 5pm Monday through Friday and 2pm on Saturdays. Post office boxes open at 7am. This branch does not process passport applications. No smoking inside, and the only animals allowed in are those assisting the handicapped.
