Biskra is the capital city of Biskra Province, Algeria. In 2007, its population was recorded as 307,987. Biskra is located in northeastern Algeria, about 248 miles (399 km) from Algiers, 71 miles (114 km) southwest of Batna and 137 miles (220 km) north of Touggourt. It is nicknamed "The Queen of the Zibans", "The Door of the Desert" or "The Saharan Nice" because of its location at the beginning of the Sahara Desert. Due to its geographical location, its climate and natural resources, particularly farming, Biskra has always been a crossroad between the cities in the north and south. It has seen the passage of several civilizations, from the Romans and the Arabs to the French.
