The Casbah (Arabic: قصبة, qaṣba, meaning citadel) is the citadel of Algiers in Algeria and the traditional quarter clustered around it. In 1992, the United Nations Educational, Scientific and Cultural Organization (UNESCO) proclaimed Kasbah of Algiers a World Cultural Heritage site, as "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."

The word kasbah may be used to describe the old part of a city, in which case it has the same meaning as a medina quarter. In Algiers, the name qasaba originally referred to the upper part of the city which contained the citadel and residence of the rulers. Following the French conquest of the country in 1830, most of the historic lower town of Algiers was demolished and remodeled along European lines. The only part of the old city that remained relatively untouched was the upper town, thus known as the "Casbah" of Algiers. Wikipedia
I have to admit I only knew of a Casbah from The Clash song Rock the Casbah. It's an interesting maze of streets and steps with an upper layer of building additions covering some of the streets. There's a lot of history and some museums in this old town area, so it's good to have a tour guide to lead the way.
I found an interesting fact regarding Pépé le Moko that was featured in a French and an American movie from the 1930s. The 1938 American movie Algiers had Charles Boyer in the movie trailer say "Come with me to ze Casbah" even though that line wasn't in the movie. The line was stuck on the actor thanks to generations of impressionists and Looney Tunes parodies.
What Looney Tunes parody? Animator Chuck Jones based the character of Pepé Le Pew, the romantic skunk introduced in 1945's Warner Bros. cartoon Odor-able Kitty, on Boyer, his voice – imitated by Mel Blanc – and the catch phrase "Come with me to ze Casbah."
A more serious and real history of the Casbah can be seen in the 1966 movie The Battle of Algiers, which depicts events in the Casbah during the Algerian War for Independence in the 1950s.
Here's what we saw at the Casbah:
