A facade is the exterior face or front of a building, often designed to be visually appealing. It serves not only as a protective barrier against the elements but also as a key element in architectural style. Facades can be made from various materials, including brick, glass, and stone, and they often reflect the cultural and historical context of the structure. In addition to buildings, the term "facade" can also refer to a deceptive outward appearance. This usage highlights how something may look attractive or convincing on the surface while concealing underlying issues or truths. This concept is often explored in literature and psychology, emphasizing the difference between perception and reality.
