The Old South Meeting House is a historic Congregational church building located at the corner of Milk and Washington Streets in the Downtown Crossing area of Boston, Massachusetts, built in 1729.

[4] After the Boston Massacre in 1770, yearly anniversary meetings were held at the church until 1775, featuring speakers such as John Hancock and Dr. Joseph Warren.

In October 1775, led by Lt Col Samuel Birch of the 17th Dragoons, the British occupied the Meeting House due to its association with the Revolutionary cause.

They destroyed much of the interior and stole various items, including William Bradford's Of Plymouth Plantation (1620), a unique Pilgrim manuscript hidden in Old South's tower.

Renowned for the protest meetings held here before the American Revolution when the building was termed a mouth-house, this National Historic Landmark has long served as a platform for the free expression of ideas.

The museum and historic site is located at the intersection of Washington and Milk Streets and can be visited for a nominal sum.
