City (pop., 2000: 11,004), capital of the island of Saint Thomas and of the U.S. Virgin Islands. Lying on St. Thomas Harbor, it was established as a Danish colony in 1672 and named for the Danish queen (its name was St. Thomas during 1921–36). The largest city in the Virgin Islands, it is built on three low volcanic spurs. Two castles, attributed to the pirates Blackbeard and Bluebeard, overlook the harbour. Tourism is economically important.
