ST. PAUL'S CATHEDRAL: THE NAVE.
Sir Christopher Wren's first thought was to build St. Paul's Cathedral in the shape of a Greek cross, but the great architect was overruled, and the present long nave and choir are the result. The Cathedral is 500 feet long, and 118 feet broad. From the point of view at which our picture is taken, the edifice looks somewhat bare, but this defect is being gradually remedied. The lower part of the dome is visible, and beyond, at the end of the choir, the altar and the marble reredos are to be seen. Beneath the central arch of the north aisle (on the left) is the monument to the Duke of Wellington, and opposite the door of the south transept, in the passage to the nave, is the memorial of Lord Nelson.
