A pergola is an outdoor garden feature forming a shaded walkway, passageway, or sitting area of vertical posts or pillars that usually support cross-beams and a sturdy open lattice, often upon which woody vines are trained. It is a type of gazebo that may also be an extension of a building or serve as protection for an open terrace or a link between pavilions. Pergolas are designed to provide a sheltered space where people can enjoy the outdoors while being partially protected from the elements, such as direct sunlight or light rain. They can be constructed from various materials including wood, metal, or vinyl, and can be designed in a range of styles to complement different architectural aesthetics. Pergolas can be freestanding or attached to a house, and are popular features in gardens, parks, and commercial outdoor spaces, providing an elegant and functional area that enhances the landscape and can be used for entertainment, dining, or relaxation.
