The United States Custom House; sometimes referred to as the New York Custom House; was the place where federal customs duties on imported goods were collected in New York City. The custom house existed at several locations over the years. From 1790 to 1799; it was at South William Street; opposite Mill Lane; known as 5 Mill Street. From 1799 to 1815; it was in the Government House; roughly on the former site of Fort Amsterdam. From 1842 it was at 26 Wall Street in a new building designed by John Frazee; that building is now Federal Hall National Memorial. From 1862 it was in the Merchants Exchange Building at 55 Wall Street. In 1907 it moved into a new building; now called the Alexander Hamilton U.S. Custom House; built on the site where Government House sat earlier; on the south side of Bowling Green. In 1973 it moved to 6 World Trade Center; which was destroyed in the September 11; 2001 attacks.
