St Catherine's College (colloquially called St Catz or Catz) is one of the constituent colleges of the University of Oxford. In 1974, it was also one of the first men's colleges to admit women. It has 528 undergraduate students, 385 graduate students and 37 visiting students as of December 2020, making it one of the largest colleges in either Oxford or Cambridge. Designed by Danish architect Arne Jacobsen, the college was built in an egalitarian architectural style that maximises the number of rooms, for academically qualified students who lacked the financial resources to study at Oxford. In September 2023, access to areas of the college was restricted due to safety concerns around the use of reinforced autoclaved aerated concrete (RAAC). The college developed out of the university's St Catherine's Society; it was granted full status as a college in 1962 by the historian Alan Bullock, who became the first master of the college, and later vice-chancellor of the university.
