The Hancock and the Adams Cannons are rare Revolutionary War cannons stolen from the British and gifted to the BHMA by an act of the Legislature in 1825.

The Hancock is presently on display at the North Bridge Visitor Center, Minute Man National Historical Park in Lexington through the courtesy of the BHMA.

The Adams is on view at the Bunker Hill Monument Lodge in Charlestown through the efforts of the National Park Service and on loan from the BHMA.
