Aesopus Bridge

The Aesopus Bridge is a late-antique stone bridge spanning the Aisepos river in ancient Mysia, northwestern Turkey — today largely a ruin. Its most remarkable feature is a hollow-chamber system built into the piers, an engineering technique also found in nearby late-antique bridges such as the Makestos Bridge, pointing to a distinct regional construction tradition beyond standard Roman practice. A field survey in the early 20th century found all four main arches collapsed, while most piers and seven smaller arches still stood. Today only two pier stumps are visible in the riverbed, with the broader structural condition difficult to assess. For those interested in late-antique engineering history, it remains a rare surviving example of bridge construction in Asia Minor.
