Outside to the rear was the State House Yard, an open public green the size of a city block and enclosed the whole way around by a seven-foot brick wall. The Rittenhouse observation platform stood off to one side, and at the center of the far wall a huge single-arched wooden gate, twice the height of the wall, opened onto Walnut Street. In good weather, as a place for the delegates to stretch their legs and talk privately, the yard was ideal. Many days more business was transacted there than inside.
