The University of Santiago de Compostela - USC (, ) is a public university located in the city of Santiago de Compostela, Galicia, Spain. A second campus is located in Lugo, Galicia. It is one of the world's oldest universities in continuous operation. The university traces its roots back to 1495, when a school was opened in Santiago. In 1504, Pope Julius II approved the foundation of a university in Santiago but "the bull for its creation was not granted by Clement VII until 1526". In 1555 the institute began to separate itself from strictly religious instruction with the help of Cardinal Juan Álvarez de Toledo and started to work towards developing other academic fields, including the emerging science fields. Today the university's facilities cover more than . In terms of human resources, the university has more than 2,000 teachers involved in study and research, over 42,000 students, and more than 1,000 people working in administration and services. Moreover, in 2009, the university received the accreditation of Campus of International Excellence by the Ministry of Education, recognising USC as one of the most prestigious universities in Spain. The university ranks 5th in Spain's best universities ranking by Complutense University of Madrid and IAIF and 4th amongst public universities. History The roots of the university go back to 1495, when the Santiago de Compostela solicitor López Gómez de Mazoa founded, with the help of the abbot of San Martiño Pinario, a school for the poor known as "Grammatic Academy" in the monastery of San Paio de Antealtares. Early on, the success of the school was in doubt due to a lack of economic resources. But in the year 1504, Pope Julius II issued a papal bull recognizing the institution and allowing for the institution of higher learning in the "Gramatic Academy". The definitive consolidation of the university comes with Alonso III de Fonseca, named archbishop of Santiago de Compostela in 1507. Fonseca was an extremely erudite man, a Renaissance man and patron of numerous artists of the time, who was in touch with important thinkers such as Erasmus of Rotterdam. At this time the old Pilgrim's Hospital was purchased with the aim of transforming it into a university college. The Santiago Alfeo College, today known as the Fonseca College, was also built, which became the centre of the university life until the second half of the 18th century and still remains
