Montaña Suiza

Montaña Suiza ("Swiss Mountain" in English) is a steel scenic railway roller coaster located at Monte Igueldo Amusement Park, on the coast at San Sebastián, Spain. It was designed and built by German engineer Erich Heidrich and opened at the site in 1928. It is the oldest steel roller coaster still operating in the world. The ride was built with wooden running rails in a trough, like usual scenic railways. The trough is partially set into the landscape and is of concrete construction. The ride lacks the traditional supporting trestles of scenic railways. Instead, the track runs in depressions set into the ground and along the top of a coastal wall at one point. The running rails were changed to steel at an unknown later date.
