Puente Nuevo. This large and incredible bridge over the Tajo gorge, finished in 1793, is Ronda's principal attraction. The bridge is 70m long and 98m high, equivalent to a 30-floor building, and connects the quarter of La Ciudad with the Mercadillo. It was built following the collapse of an earlier bridge from 1735; this bridge had a single arch of 35m but collapsed six years after construction, killing 50 people. There are beautiful views from here of the Sierra de Grazalema to the west. A small museum is inside.
