Freedom Trail attraction. The congregation, organized in 1686, built this chapel in 1688-1689 on a graveyard. It was rebuilt from 1749-1754 and still stands here today. Many now-famous people worshipped here, including George Washington, Royal Governor Hutchinson and Oliver Wendell Holmes. For a unique spin on history, take the Bell and Bones Tour, which visits the building's 200-year-old crypt, $5-7. Self-guided tours also available (suggested donation $2). Open F-M for guided tours, but schedule varies in off-season; call ahead.
