A skatepark is a purpose-built recreational environment made for skateboarding, BMX and aggressive inline skating. A skatepark may contain half-pipes, quarter pipes, spine transfers, handrails, funboxes, vert ramps, pyramids, banked ramps, full pipes, pools, bowls, snake runs stairsets, and any number of other objects. The first skatepark in the world, Carlsbad Skatepark, in Carlsbad, California, was designed and built by inventors Jack Graham and John O'Malley in March 1976. In more extreme climates parks were built indoors, often of wood or metal. By the end of 1970s the skateboarding fad had waned, and the original parks of the era began to close. A downturn in the general skateboard market in the 1980s and high liability insurance premiums contributed to the demise of the original skateparks. Some second-generation parks such as Upland, California's Pipeline survived into the 1980s.
