The treatment of the latter wall of the hall is most elaborate. Three cased arches correspond to the open arches opposite. On the wall within the two end ones are handsome, pedimental-topped, inscribed tablets, while in the middle one is located the doorway with an ornate, broken, pedimental doorhead taking the form of a swag.
Like the hall, the Supreme Court chamber is Doric with fluted pilasters instead of engaged columns, and walls entirely paneled up. There are three windows at each end and two back of the judge's bench with its paneled platform and rail, and balustraded staircases at each end. In this room the convention to form a new constitution for Pennsylvania met July 15, 1776, and unanimously approved the Declaration of Independence, and pledged the support of the State. Delegates to Congress were elected who were signers of the Declaration. In this room now stands the statue of Washington carved out of a single block of wood by Colonel William Rush, after Stuart.
Across the hall is the Declaration chamber, forty feet and two inches long, thirty-nine feet and six inches wide and nineteen feet and eight inches high. As in size, its architecture is substantially the same as the chamber opposite, and like it the two corners near the hall are rounding. Also it is of spacious appearance, light, beautiful and cheerful, a room to inspire noble deeds. Instead of the high judge's bench at the side opposite the entrance, there is a relatively small platform or dais of two steps on which stands the presiding officer's desk in front of a large, elaborate, pedimental-topped frame with exquisitely enriched carved moldings, within which is a smaller frame containing a facsimile of the Declaration of Independence. To either side, between fluted pilasters, are segmental arched fireplaces with heavy mantel shelves above, supported by carved consoles, while beyond these are single doors with pedimental heads. Otherwise the room is substantially like that across the hall. They are regarded as the best of the restored rooms of the building, and of the two the courtroom is perhaps rather the better in its greater simplicity.
In the east or so-called Declaration chamber, the second Continental Congress met May 10, 1775; George Washington was chosen commander in chief of the Continental Army June 15, 1775; and the Declaration of Independence was adopted July 4, 1776. The American officers taken prisoners at the Battle of Brandywine, September 11, and of Germantown, October 4, 1777, were held here as prisoners of war, and on July 9, 1778, the Articles of Confederation and perpetual union between the States were signed here by representatives of eight States. The room contains much of the furniture of those days. The table and high-backed Chippendale chair of mahogany used by the presidents of the Continental Congress and occupied by John Hancock at the signing still remain, and on the table is to be seen the silver ink-stand with its quill box and sand shaker, in which the delegates dipped their pens in autographing the famous document. There are also fourteen of the original chairs used by delegates. On the walls hang portraits of forty-five of the fifty-six signers, also a portrait of Washington by Rembrandt Peale.
