Algeria, predominantly Muslim country, is considered the largest country in Africa, with over four-fifths of its territory covered by the Sahara desert. It is a country located in Northern Africa bordering the Mediterranean Sea. It is considered the gateway between Africa and Europe. 

​

Many empires have left legacies here, such as the ancient Roman ruins in seaside Tipaza. In the capital, Algiers, Ottoman landmarks like circa-1612 Ketchaoua Mosque line the hillside Casbah quarter, with its narrow alleys and stairways. The city’s Neo-Byzantine basilica Notre Dame d’Afrique dates to French colonial rule.
