Dezful, in the Khuzestan Province, Iran, and is known for its ancient fortified bridge, which dates from 300 BCE. In fact, the name Dezful derives from the words for fortress and bridge, meaning ‘fortified bridge’. The area itself, the Chogha Mish hills, has been occupied for 8,000 years. Adjacent to the bridge is a castle and the remains of several water mills, built at roughly the same time as the bridge. Many of the mills were in use until the early 20th century.
