Batroun is a coastal city in northern Lebanon lying 50 km north of Beirut and 30 km south of Tripoli. It is one of the oldest cities in the world with a history of human occupation going back to at least 5,000 years. The sea wall was originally a natural structure composed of petrified sand dunes. This was reinforced by the Phoenicians with rocks and the process went on until it took its present shape in the first century B.C. The wall is 225 meters long and 1 to 1.5 meters thick. Parts of it has crumbled but the remaining still stand strong and proud in Batroun’s bay, and is a must see for an authentic piece of Lebanon’s ancient history.
