During late antiquity the gradual abandonment and dissolution of the Hellenistic fortifications, which were transformed into actual areas of building material quarrying for the construction of the Byzantine and knight walls and other buildings, is documented. Its use as unfortified platform-pier from old Christian until post-Byzantine years was ascertained. The construction of the windmills on the rocky protection of the beach at the eastern side of the mole dates back to the middle of the 13th century. The gradual expansion of the walled knight’s town to the east during the first half of the 15th century, after the initial uncertainty regarding the habitation of the Upper Hebrew district was overcome, resulted in the southern part of the mole definitely disappearing, since it was included in the residential segment of the town. The "gate of the mole", known today as Saint Catherine’s Gate, the existence of which is already documented since 1391, was leading to the interior of the medieval mole.
