A pergola is an outdoor structure typically made of vertical posts or pillars that support crossbeams and an open lattice roof. It is often used to create a shaded walkway, passageway, or sitting area in gardens and yards. Pergolas can be constructed from various materials, including wood, metal, or vinyl, and can be freestanding or attached to a building. These structures enhance outdoor spaces by providing partial shelter while allowing sunlight to filter through. They can be adorned with climbing plants, such as vines or flowers, to create a more natural and inviting atmosphere. Pergolas are popular for entertaining and relaxation.
