The bank's Art Deco headquarters building at 292 Cambridge Street in East Cambridge, Massachusetts was built in 1931 to a design by T. M. James. It has a triple-arched front facade, an element repeated on the side with three similarly scaled round-arch windows. Bands of carving adorn an entablature band at the top of the main wall, and on a stepped back section above. The building's interior includes sculpture by Paul Fjelde and murals painted by Alfred Rasmussen.[2] The building was listed on the National Register of Historic Places in 1982.[1]
