Boston’s constant churning of development has given us amazing architectural landmarks, and incredibly unfathomable architectural loss. One of such cases of loss is the former Brattle Street Church which was located on Brattle Street, roughly where the main entrance to Boston City Hall is located today. Demolition of significant architecture in Boston began way before the period of Urban Renewal in the mid-20th century, and the loss of the Brattle Street Church in Downtown Boston showcases this. The Brattle Street Church had been founded in the 1690s by a group of merchants seeking an alternative to the authority exercised by Increase and Cotton Mather in Boston’s existing congregations. Despite these beginnings, the church remained Congregational through the 18th century. At the time of the Revolution, Brattle Street counted such figures as John Hancock, Samuel Adams, Joseph Warren, and John and Abigail Adams among its parishioners. The original wooden church was replaced in 1772 by this stunning brick building, designed by Thomas Dawes. Just years after the doors opened, the American Revolution upended life in Boston. This building was a survivor, and was apparently hit by cannon-fire by the American batteries at the siege of Boston. A cannonball can be seen lodged into the building at the second floor, to the right of the Palladian window. After the American Civil War, development of the Back Bay led to a shifting population away from the downtown core, and a new church was erected for the congregation, the Brattle Square Church, designed by Henry Hobson Richardson. This church was demolished in 1872, just 100 years after it opened its doors and took a cannon for America.
