Park Street Church is an evangelical congregation in downtown Boston founded in 1809 at the corner of Park and Tremont Streets, overlooking Boston Common. Historically nicknamed "Brimstone Corner," it is a member of the Conservative Congregational Christian Conference rather than the United Church of Christ. The church's 217-foot steeple was the tallest structure in the United States from 1810 to 1828, and the building is a stop on Boston's Freedom Trail.
