History Archaeological remains have been found in the limits of St. Paul's Bay, which go back to around 4000 BC. Among the remains there are the megalithic temples of Buġibba and Xemxija. In addition, Cart Ruts were found on the Wardija Ridge at Busewdien, while Punic tombs and other Bronze Age remains were also found. During the Roman period, St. Paul's Bay became an important harbour. Remains of a Roman road, baths and beehives, have been found at Xemxija, while Roman anchors were found on the seabed. By the late Middle Ages, St. Paul's Bay was abandoned since the area was unsafe due to corsair raids. The local militia maintained several watch posts in the area. One of these, known as Ta' Tabibu farmhouse, still survives today and is considered to be the oldest building in St. Paul's Bay. A building of a church was also noted at the arrival of the Order of St John in 1530. A number of fortifications were built in the area during the rule of the Order of Saint John. The first of these was the Wignacourt Tower, built in 1610, which is now the oldest surviving watchtower in Malta. Qawra Tower was built by Grand Master Lascaris in 1638. In 1715, batteries were built around these two towers, while two batteries and a redoubt were built in other parts of the St. Paul's Bay coastline.
