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.

Modern pergola design material including wood, vinyl, fiberglass, aluminum, and chlorinated polyvinyl chloride (CPVC) rather than brick or stone pillars, are more affordable and are increasing in popularity.
