The lower lobby offers an excellent example of the intricate craftsmanship of early South Carolina brickwork. To construct the multi-arched ceiling, which is made of red clay bricks, the builders and brick masons wet the wooden beams of the ceiling and bent them to shape. Then, the bricks were inserted one by one. It took 20 years to complete the ceiling. In order to brighten the lower lobby, the brickwork has been painted white.
