The Custom House Block, built in 1845-87 in Boston, Massachusetts, is a former warehouse located on Long Wharf, at the end of State Street. Architect Isaiah Rogers designed the four-storey building, constructed of granite and brick. In its 19th-century heyday, it contributed to the life of "Boston's busiest pier, commercial port, and embarkation point for travelers." Today private owners maintain the site. The building was renovated in 1973 by Anderson, Notter, Feingold.
