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 1817 to 1834, it was in a converted bookstore and reading room on
Wall Street at the east side of
Nassau Street. That building was demolished for construction of a new Custom House at the same location, completed in 1842, which was designed by
John Frazee, and is today designated
Federal Hall National Memorial. From 1862 it was in the Merchant's 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. and moved the custom house there in 1973. After the
World Trade Center was destroyed during the
September 11 attacks in 2001, employees were moved to various places in
Manhattan,
Queens, and
Elizabeth in
New Jersey. The Customs Service was split into several agencies in 2003. One of its successors,
U.S. Customs and Border Protection, planned to return to the new
World Trade Center, moving into
One World Trade Center. ==Importance==
