Charlotte Amalie, located on the island of St. Thomas, is the capital and the largest city of the United States Virgin Islands, founded in 1666 as Taphus . In 1691, the town was renamed to Amalienborg (in English Charlotte Amalie) after Charlotte Amalie of Hesse-Kassel (1650–1714), queen consort to King Christian V of Denmark-Norway. It has a deep-water harbor that was once a haven for pirates and is now one of the busiest ports of call for cruise ships in the Caribbean, with about 1.5 million cruise ship passengers landing there in 2004. Protected by Hassel Island, the harbor has docking and fueling facilities, machine shops, and shipyards and was a U.S. submarine base until 1966. The town has been inhabited for centuries. It is on the southern shore at the head of Saint Thomas Harbor. In 2010 the city had a population of 18,481, which makes it the largest city in the Virgin Islands Archipelago. Hundreds of ferries and yachts pass through town each week, and at times the population more than doubles.
The city is known for its Danish colonial architecture, building structure and history, and a dozen streets and places throughout the city have Danish names. Charlotte Amalie has buildings of historical importance including St. Thomas Synagogue, the second-oldest synagogue in the Western Hemisphere, and Frederick Lutheran Church, the oldest Lutheran church in the Western Hemisphere. The town has a long history of pirates, especially stories of Bluebeard and Blackbeard (Edward Teach). In the 17th century, the Danes built both Blackbeard's Castle and Bluebeard's Castle attributed to the pirates. Blackbeard's Castle is a U.S. National Historic Landmark. Another tourist attraction is Fort Christian, the oldest standing structure in the Virgin Islands Archipelago. A copy of the Liberty Bell is in Emancipation Park, which is a tourist attraction.
