The meeting house or church was completed in 1729, with its 56 m steeple. The congregation was gathered in 1669 when it broke off from First Church of Boston, a Congregational church founded by John Winthrop in 1630. The site was a gift of Mrs. Norton, widow of John Norton, pastor of the First Church in Boston. The church's first pastor was Rev. Thomas Thatcher, a native of Salisbury, England. Thatcher was also a physician and is known for publishing the first medical tract in Massachusetts. 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 1773, 5,000 people met in the Meeting House to debate British taxation and, after the meeting, a group raided three tea ships anchored nearby in what became known as the Boston Tea Party. 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 gutted the building, filled it with dirt, and then used the interior to practice horse riding. They destroyed much of the interior and stole various items, including William Bradford's Of Plymouth Plantation, a unique Pilgrim manuscript hidden in Old South's tower. After the British evacuated Boston, the plan for rebuilding the interior of the church was drawn by Thomas Dawes. Old South Meeting House was almost destroyed in the Great Boston Fire of 1872, saved by the timely arrival of a fire engine from Portsmouth, New Hampshire, but the fire caused the city's residential districts to shift toward the Back Bay, away from the church. The congregation then built a new church building which remains its home to this day. The Old South congregation returns to Old South Meeting House for services in its ancestral home once a year, on the Sunday before Thanksgiving.
Old South Meeting House has been an important gathering place for nearly three centuries. 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. Today, the Old South Meeting House is open daily as a museum and continues to provide a place for people to meet, discuss and act on important issues of the day. The stories of the men and women who are part of Old South's vital heritage reveal why the Old South Meeting House occupies an enduring place in the history of the United States. The museum and historic site is located at the intersection of Washington and Milk Streets and can be visited for a nominal sum. It is located near the State Street, Downtown Crossing and Park StreetMBTA stations. The Old South Meeting House is claimed to be the second oldest establishment existent in the United States. It is currently under consideration for local landmark status by the Boston Landmarks Commission. In 2020 the former caretaker of Old South Meeting House merged with the Bostonian Society, forming Revolutionary Spaces, which now manages both Old South Meeting House and the Old State House.
