The Lahaina Arts Society, Lahaina Vistor Center, and Lahaina Heritage Museum occupy this charming old government building in the center of town. Wander among the terrific displays and engage with an interactive exhibit about Lahaina's history, pump the knowledgeable visitor center staff for tips—plus ask for the walking-tour brochure covering historic Lahaina sites—and stop at the theater with a rotating array of films about everything from whales to canoes. Erected in 1859 and restored in 1999, the building has served as a customs and court house, governor's office, post office, vault and collector's office, and police court. On August 12, 1898, its postmaster witnessed the lowering of the Hawaiian flag when Hawaii became a U.S. territory. The flag now hangs above the stairway. There's a public restroom in the building.
