A large, heavy ship, scuttled between 1775 and 1798, is being dug out of its damp grave at the site of a new hotel construction project in Old Town Alexandria. Archaeologists found the partial hull of a ship at 220 S. Union Street, part of the city's major redevelopment of the Potomac River waterfront. It's on the same one-block site where workers two months ago discovered a 1755 foundation from a warehouse that is believed to have been the city's first public building.
