Dating from 1729, Boston’s Old South Meeting House was a congregational church and a social occasion place for protestors who sparked the American Revolution with the 1773 Boston Tea Party. A critical site on Boston's Freedom Trail, the block building is currently an exhibition hall where guests can graph the beginnings of the country's 1776 insurgency. A US National Historic Landmark, the Old South Meeting House was a mobilizing point for eighteenth century pioneers restricted to British guideline. In December 1773, a gathering went out to dump tea from three British tea ships into Boston Harbor—an occasion known as the Boston Tea Party.
