Old Akko wall, Stone fortification in Acre, Israel.

The Old Akko wall is a stone fortification encircling the old city of Acre. Its landward side has three parallel lines: the wall with towers, a deep moat, and protruding bastions. The sea wall, largely built by Zahir al-Umar and strengthened by Ahmad al-Jazzar, rises directly from the water. The wall is about 10 to 13 meters high and one meter thick, with small watchtowers on top.

The wall was rebuilt in the 18th century by Ottoman rulers, who reused stones from an earlier Crusader fortress. This rebuilding created a double structure with earth between the layers, strengthening its defensive power.

The walls show traces of different peoples who lived and built here, from the Phoenicians to the Ottomans. You can see this layered history in the varying stone types and construction methods stacked upon one another.

Access to the wall is through marked entrances, and viewing points are positioned along the route. From these spots you can see both the Mediterranean and the city below.

The western Poterna section holds hidden tunnels that served as escape routes over the centuries. Local residents used these passages during sieges and times of conflict.
