The Pont del Diable (Spanish: Puente del Diablo, English: Devil's bridge) is a medieval bridge crossing the river Llobregat in Martorell-Castellbisbal, Catalonia, Spain. The present bridge, featuring a large pointed arch, was constructed in 1283 on Roman foundations. The main clear span is an impressive 37.3 m with a stone chapel on top. A secondary arch has a span of 19.1 m. The bridge was destroyed in 1939 during the Spanish civil war by retreating Republican troops, but rebuilt in 1965 in a form generally similar to the gothic structure.
The bridge features a Roman triumphal arch at its eastern abutment. It is unclear how many spans the original Roman bridge had. Today the bridge is restricted to pedestrians.
