The survey and the excavations that followed it allowed for an examination of the fortifications in Hippos from the Late Hellenistic to the Roman period, and finally to Byzantine and Umayyad periods when the defensive wall turned into merely a boundary wall of the city. The line of the walls that can be distinguished today along the mountain cliffs are mostly later than the Roman period. However, it still follows the line of cliffs as the line of fortifications had done before it. This means that the length of the walls during the Hellenistic and Roman periods was not noticeably different, about 1550m. No evidence has been found for fortifications of the Early Hellenistic period that could have been ascribed to a fortress of the Ptolemaic or Seleucid period.
