Fort Christian, Charlotte Amalie, St Thomas. According to Wikipedia: "Fort Christian is a Dano-Norwegian-built fort in Charlotte Amalie, Saint Thomas, U.S. Virgin Islands. Built 1672-1680, early in the first successful colonial establishment on the island, the fort served as a critical point of defense and government during the entire period of Dano-Norwegian, and later Danish, administration, which ended in 1917 with the sale of the islands to the United States. It currently holds the St. Thomas Museum, which holds artifacts and art of the Dano-Norwegian period."
