[1] The former customshouse is set on the south side of Main Street just east of Barnstable's municipal complex.

It is a two-story brick building with late Italianate styling, designed by Ammi Young and built in 1855.

Its door and window openings have round-arch tops highlighted by light-colored trim.

The post office moved out in 1958, and the federal government turned the building over to the town in 1960.
