The University of Santo Tomas (UST) is the oldest existing university in Asia. In terms of student population, it is the largest Catholic university in the world in a single campus. The institution was established through the initiative of Bishop Miguel de Benavides, O.P., third Archbishop of Manila. On July 24, 1605, he bequeathed the amount of one thousand five hundred pesos and his personal library for the establishment of a “seminary-college” to prepare young men for the priesthood. Those funds, and his personal library, became the nucleus for the start of UST and its library.
