Buckman Tavern is a historic American Revolutionary War site associated with the revolution's very first battle, the 1775 Battle of Lexington and Concord. It is located on the Battle Green in Lexington, Massachusetts and operated as a museum by the Lexington Historical Society.
Part of an American Revolutionary War battle took place inside Buckman Tavern. 
It says the tavern was "associated with" a battle, not that a battle actually took place inside it -- whether that's true isn't made clear from the context.
