Salamanca, a city of the autonomous community of Castilla y Leon is located adjacent to the River Tormes.Salamanca is famous mainly for two reasons: for possessing one of the oldest and most prestigious universities in Spain and for its architectural heritage.With the fall of the Carthaginians to the Romans, the city began to acquire some importance. It soon became a core business enclave due to its privileged location beside the River Tormes. The invasion of the peninsula by the Muslims in 711 meant the conquest of Salamanca from 712 until the tenth century, when it was in Christian hands again.In the thirteenth century, the monarch Alfonso IX of Leon gave the schools of the cathedral the rank of General Studies in 1253, thus becoming the University of Salamanca by royal charter of Alfonso X. The university achieved great prestige .The sixteenth century was an era of great glory for the city, both in demographics and in university life, thanks to the prestige of their teachers, with the so-called School of Salamanca.
