The United States Custom House, on Bank Street in New London, was built in 1833 and was designed by Robert Mills, architect of the Washington Monument in Washington, DC. The wood doors are made from planks from the USS Constitution. When the Amistad was brought to New London in 1839, the ship was moored near the Custom House and when it was sold, in 1840, its cargo was auctioned off in the building. The New London Maritime Society was formed in 1983 to save the Greek Revival-style building. It established the New London Custom House Maritime Museum in what continues to be the oldest continuously-operating custom house in the country.
Custom House, New London (1833)
New London has a large collection of historic buildings. I walked around there last fall, and was amazed by a lot of them.
