Friends meeting houses are places of worship for the Religious Society of Friends, or Quakers. A "meeting" is the equivalent of a church congregation, and a "meeting house" is the equivalent of a church building. One of the key tenets of the Religious Society of Friends is pacifism, adherence to the Peace Testimony. The "Free Quakers" were supporters of the American Revolutionary War, separated from the Society, and built their own meeting house in Philadelphia, at 5th & Arch Streets (1783).
