St. Thomas is a steep, green island in the U.S. Virgin Islands, and its main town, Charlotte Amalie, is the territory's capital, spread around a deep natural harbor.
Danish colonial streets climb Government Hill to landmarks such as red-walled Fort Christian, the 99 Steps, Blackbeard's Castle and the 1803 St. Thomas Synagogue. The islands passed from Denmark to the United States in 1917; the US dollar is the currency, and cars drive on the left.
Visitors come for duty-free shopping on Main Street, the white sand of Magens Bay, snorkeling at Coki Point and ferries to St. John. It is one of the Caribbean's busiest cruise ports.
