The Casbah, a unique urban walled area, has been described by UNESCO as ‘one of the finest coastal sites on the Mediterranean’. It is sited on the ruins of an ancient Roman city that legends say was founded by companions of Hercules. It is a tight knit warren of alleys where white washed houses lean so close they cut out the sharp sun for most of the day. The Casbah has been featured in many popular films and songs and played an important role in the War of Independence. Although in much disrepair now, it is a fascinating highlight of any visit to Algiers.
