Puente Nuevo is the newest and largest of three bridges that span the 390 ft chasm that carries the Guadalevín River and divides the city of Ronda. It was started in 1759 and took 34 years to build. There is a chamber above the central arch that was used for a variety of purposes, including as a prison. During the 1936–1939 civil war both sides allegedly used the prison as a torture chamber for captured opponents, killing some by throwing them from the windows to the rocks at the bottom of the El Tajo gorge
