A pilaster is a vertical architectural element that resembles a column but is attached to a wall rather than standing independently. It typically has a rectangular shape and serves both decorative and structural purposes. Pilasters can be found in various architectural styles, including Classical, Roman, and Gothic designs, and they often feature bases, shafts, and capitals similar to those of free-standing columns. In addition to their aesthetic appeal, pilasters can help support the weight of the structure above them, providing stability to walls. They are commonly used in buildings, such as temples, churches, and government buildings, to enhance the overall design and create a sense of grandeur.
