Cypriot bichrome ware, hard to find even in Cyprus, has also turned up at Dor. Archaeologists found these sherds on the clay floors of large public buildings, built mostly of mudbricks, that they uncovered in area B1. The sherds, and hence the buildings, are securely dated to the late 11th century B.C.E. and are the remains of the first Phoenician city at Dor. The Cypriot pottery may be the telltale sign of trade between Dor and Phoenician colonies on Cyprus, which some archaeologists believe were already established at this time.
