Pergola

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. The origin of the word is the Late Latin pergula, referring to a projecting eave. As a type of gazebo, it may also be an extension of a building or serve as protection for an open terrace or a link between pavilions. They are different from green tunnels, with a green tunnel being a type of road under a canopy of trees.

Pergolas are sometimes confused with arbours ('arbors' in American English), and the terms are often used interchangeably. An arbour is generally regarded as a wooden bench seat with a roof, usually enclosed by lattice panels forming a framework for climbing plants. A pergola, on the other hand, is a much larger and more open structure and does not normally include integral seating.

Pergolas may link pavilions or extend from a building's door to an open garden feature such as an isolated terrace or pool. Freestanding pergolas, those not attached to a home or other structure, provide a sitting area that allows for breeze and light sun, but offer protection from the harsh glare of direct sunlight. Pergolas also give climbing plants a structure on which to grow. Pergolas are more permanent architectural features than the green tunnels of late medieval and early Renaissance gardens, which were often formed of springy withies—easily replaced shoots of willow or hazel—bound together at the heads to form a series of arches, then loosely woven with long slats on which climbers were grown, to make a passage that was both cool and shaded and moderately dry in a shower. At the Medici villa, La Petraia, inner and outer curving segments of such green walks, the forerunners of pergolas, give structure to the pattern, which can be viewed from the long terrace above it.
