BOSTON (AP) — A shipwreck from the 1800s has been uncovered during construction in Boston's Seaport District.

City archaeologist Joe Bagley said it's the first time a shipwreck has been found in that section of the city, a trendy waterfront area with office buildings, expensive condos and upscale restaurants.

The vessel was uncovered last week during construction of a 17-story office building. It appears to be partially burnt.

New York-based construction company Skanska USA has been meeting with city officials to discuss the discovery, and archaeologists have been studying the vessel and taking measurements.

Shawn Hurley, a Skanska executive, said work has been halted for almost a week because of the find.

"There are certainly impacts, but we'll work through them," he said.

The area was once mudflats that alternated between dry land and water based on the tides, so ships "kind of sailed right over" the property, Bagley said. In the late 1800s, that section of Boston Harbor was filled in.

He said it appears the vessel had a load of lime, which was used for masonry and construction.

The lime was likely brought to Boston during a 19th century building boom, he said. Bagley called it remarkable that the ship was found now, during another building boom in the city.

"They're really part of the same narrative of Boston growing as a city," he added.
