Granada is located at the foot of the Sierra Nevada mountains, at the confluence of four rivers, the Darro, the Genil, the Monachil and the Beiro. It is only one hour by car from the Mediterranean coast, the Costa Tropical. The Alhambra, a Moorish citadel and palace, is in Granada. It is the most renowned building of the Andalusian Islamic historical legacy with its many cultural attractions that make Granada a popular destination among the tourist cities of Spain. The Almohad influence on architecture is also preserved in the Granada neighborhood called the Albaicín with its fine examples of Moorish and Morisco construction. Granada is also well-known within Spain for the University of Granada which has an estimated 82,000 students spread over five different campuses in the city. The pomegranate (in Spanish, granada) is the heraldic device of Granada.
