For example, the balustrade of the 16th century Basilica St. Peters at the Vatican is truly Renaissance architecture. The baluster has come to be known as any vertical brace (often a decorative post) between an upper and lower horizontal railing. Staircases and porches often have balustrades or rails of balusters. The purposes of balusters are for safety, support, and beauty. Today's balusters are constructed of wood, stone, concrete, plaster, cast iron or other metal, glass, and plastics.
