Apparently, the true location isn’t known anyways. And there’s a museum located nearby dedicated to it.
The Beaver, Dartmouth, and Eleanor were moored at Griffin’s Wharf in Boston. It is at this location where the December 16, 1773 destruction of the tea occurred. The original location of the Boston Tea Party no longer exists because of extensive landfills that destroyed the location. This was caused by the city of Boston’s rapid expansion in the 19th century. In 18th century Boston, Griffin’s Wharf was a bustling center for maritime commerce and shipping. The exact location of the original Griffin’s Wharf is open to debate, but the Boston Tea Party Ships & Museum, located on the Congress Street Bridge, is located near the approximate area where the Boston Tea Party took place. A historical marker commemorating the Boston Tea Party stands on the corner of Congress and Purchase streets.
