The Dyavolski most (Bulgarian: Дяволски мост, lit.

It is 10 km (6.2 mi) from the Bulgarian town of Ardino in the Rhodope Mountains and is part of the ancient road connecting the lowlands of Thrace with the north Aegean Sea coast.

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 for reading the water level.

A stone parapet, 12 cm (4.7 in) tall, is preserved on the sides, and breakwaters are placed opposite the stream.
