What was found under the Twin Towers after 9 11?

The World Trade Center (WTC) attack, which took place on September 11th, 2001, left the world in shock; however, in the midst of this tragedy and chaos, cleanup crews discovered something amazing. In 2010, buried underneath the ruins of the Twin Towers, we found the remains of a large ship's hull.



During the deep excavation for the new World Trade Center site, archaeologists made a stunning discovery in 2010: the remains of a Revolutionary War-era wooden ship. Buried more than 20 feet below street level, the vessel was likely a Philadelphia-built sloop from the 1770s that was deliberately sunk in the late 18th century as "landfill" to expand the shoreline of Manhattan into the Hudson River. Beyond the ship, excavators found thousands of smaller artifacts, including 18th-century shoes, ceramic jars, and animal bones, providing a rare glimpse into colonial New York life. These findings were preserved by the oxygen-free mud of the riverbed. In 2026, these artifacts are primarily housed at the New York State Museum and studied by institutions like Texas A&M. They serve as a poignant reminder that the site of the 9/11 tragedy has layers of history stretching back centuries before the towers were ever conceived.
