As per UNESCO WHS website:

The Kasbah is a unique kind of medina, or Islamic city. It stands in one of the finest coastal sites on the Mediterranean, overlooking the islands where a Carthaginian trading-post was established in the 4th century BC. There are the remains of the citadel, old mosques and Ottoman-style palaces as well as the remains of a traditional urban structure associated with a deep-rooted sense of community.

Algiers is the capital and largest city of Algeria, and the second largest city in the Maghreb.
