In the 1950s, after the university constructed Walsh Hall and the de Saisset Museum on two of the last remaining open spaces on the old college campus, Santa Clara began purchasing and annexing land from the surrounding community. The first addition, which occurred slightly earlier,[when?] brought space for football and baseball playing fields. Thereafter, particularly in the 1960s when women were admitted to the school, more land was acquired for residence halls and other new buildings and facilities.
