A pergola is an outdoor structure or architectural feature that consists of vertical posts or columns supporting a series of crossbeams or open lattice roof. It typically provides a partially shaded space, often used in gardens, patios, or outdoor areas, creating an inviting and visually appealing space for relaxation, dining, or entertaining. Pergolas can be made from various materials such as wood, metal, or vinyl and can be customized in design and size to suit individual preferences and needs.
