The Customs House chronicles the history of Key West. In the 1820s, the city became an official port of entry to the United States, permitting cargo salvaged from wrecked ships to be legally brought here for sale. Eventually, that booty made Key West the richest spot in Florida. The red brick and terracotta Customs House features a main gallery of rotating art exhibits and smaller galleries with exhibits related to Key West history. Admission is $6 for adults, $4 for children aged 12 and under.
