Walls of Thessaloniki, Byzantine fortification system in Thessaloniki, Greece
The defensive walls extend for 4.3 kilometers around Thessaloniki, featuring rectangular towers and triangular bulwarks along their northern section.
Construction of the walls began in 316 BC under Cassander, with major expansions during the 4th century AD under Emperor Theodosius.
The fortifications incorporate architectural elements from ancient structures, including marble benches and architraves from demolished Roman buildings.
Visitors can access multiple sections of the walls throughout the day, with the best-preserved portions located near the Trigonio Tower.
The walls contained an underwater barrier made of ancient sarcophagi and funeral stones, placed to prevent naval attacks during the 904 Saracen siege.
