A balustrade is a protective barrier that is often found along staircases, balconies, and terraces. It consists of a series of vertical posts, called balusters, that support a top rail. Balustrades not only enhance safety by preventing falls but also add an aesthetic touch to a space, making them popular in both residential and commercial buildings. These structures can be made from various materials, including wood, metal, and glass, allowing for diverse designs. In historical architecture, such as in many European castles and mansions, balustrades often feature intricate carvings and details, showcasing the craftsmanship of the time.
