Surrounding Wall of the Casbah, Alger (must see)

The present wall is just a small piece of the massive original wall that surrounded the city. The wall was built so that local inhabitants would remain safe from attacks by English, Spanish and French warriors. It was raised by the Barberousse brothers, and the project was finished in 1542. The wall protected an area of seventy hectares and reached a height of eleven to thirteen meters. The locals are very fond of the remaining wall and treasure it as a symbol of freedom.
