Located on the west side of Battery Park, the American Merchant Mariners’ Memorial is a haunting tribute to commercial seamen who lost their lives, for whatever reason, on the water. The memorial, was based on a true event during World War II, in which a Nazi U-boat attacked an American merchant marine vessel. While the marines held on to their sinking vessel, the Nazis photographed the victims, then left. The memorial is directly inspired by one of those photographs. Very moving.
