THESSALONIKI WALLS

The ramparts visible on the heights of the city were built in medieval times. One notices however in the walls some pieces brought back from older monuments or earlier fortifications that can, without certainty, be traced back to the time of the first ramparts of Cassandra. The walls are the work of the Roman Emperor Theodosius I and the Persian Hormisdas, as indicated by a 9 m long inscription on the upper part of the Hormisdas tower (only part of it has survived).

This fortification was built against the Roman wall, so that they reinforced each other. At the same time, many towers (60 are visible today, including the White Tower) were erected at regular intervals to reinforce the ramparts and protect the very vulnerable lower town. The perimeter of the fortifications reached up to 7 km, of which only 3 km are preserved today. The height of the walls varies from 8.30 m to 10.50 m. Built largely of stone and mortar, they regularly give way to strips of brick which increase the solidity of the building.

The most imposing part of the old fortifications is certainly the White Tower. Overlooking the port of Thessaloniki, it has become its emblem. The tower was probably built by the Turks on the ruins of an older tower, unless it was the work of the Venetians who occupied the city before the Turks.
