The largest caravanserai in Israel, dating from the late 18th century. It was built by Ahmad Pasha al-Jazzar using columns from Roman Caesarea — "Khan el-Umdan" means "khan of the columns," and the ancient granite and marble pillars that line the ground floor make the derivation immediately obvious.
The inner courtyard is enormous: traders, their goods, and their animals could all shelter here. Today the khan is partially restored, and the courtyard serves as an outdoor eating area in the evenings. The clocktower added in 1906 rises above the harbour entrance and provides a useful landmark. The whole complex is right at the edge of the harbour, with fishing boats moored just outside.
