A pergola is an outdoor garden structure that forms a shaded walkway or seating area, consisting of vertical columns supporting crossbeams and an open lattice. It is often covered with climbing plants to provide shade and natural beauty. A pergola can extend from a building, connect two structures, or shelter an open terrace. It creates a relaxing space and adds architectural depth to gardens and patios. Pergolas are made from wood, metal, or other materials and can be designed to complement the architectural style of the surroundings.
