Location

Dyavolski most was rebuilt between 1515 and 1518 by the Bulgarian Master Dimitar. Legend has it that the bridge was built by the Romans to link the Aegean Sea and the region of Thrace in Bulgaria. The bridge, the largest and best known of its kind in the Rhodopes, is 56 m (183.7 ft) long and has three arches, but also features holes with small semicircular arches to read water level. The Dyavolski most is 3.5 m (11.5 ft) wide and its main arch is 11.50 m (37.7 ft) high. A stone parapet, 12 cm (4.7 in) tall, is preserved on the sides, and breakwaters are placed opposite the stream.^[1]

International long-distance hiking trail the Sultans Trail passes the bridge from Ardino to Kardzhali.

The bridge was proclaimed a monument of culture on 24 February 1984.^[1]
