In architecture, a pavilion is a free-standing structure that is usually lightweight and designed for temporary or semi-permanent use. Pavilions are often used for outdoor events, such as exhibitions, trade shows, festivals, and concerts, and can be found in parks, public squares, and gardens. They may be open or enclosed, and their design can vary from traditional to modern, depending on their intended use and the environment in which they are situated. Pavilions are typically smaller than a building and can be designed to be easily assembled and disassembled for transport and storage. They often serve as a focal point or gathering place for social events or as an extension of a larger structure or landscape.
