Ateneo de Manila University
Within this campus is the Rizal Library, the main university library. Also located here are numerous units and research centres affiliated with Ateneo, such as the Institute of Social Order, Institute of Philippine Culture, Institute on Church and Social Issues, Asian Public Intellectuals Fellowships, the Philippine Institute for Pure and Applied Chemistry, the Jesuit Communications Foundation, the Jesuit Basic Education Commission, and others. Also situated here are the East Asian Pastoral Institute, Loyola School of Theology, and San Jose Seminary, all Jesuit formation institutions federated with the Ateneo de Manila University. The Manila Observatory is also located on campus.
Athletic facilities include the Blue Eagle Gym, also known as the Loyola Center, standing at the southern end of the campus, and the Moro Lorenzo Sports Center (MLSC) on the northern end. The Blue Eagle Gym is one of the largest gymnasiums among the universities in Metro Manila while the MLSC is often used by the Philippine National Basketball Team as well as other professional teams for their training needs.
University Athletic Association of the Philippines
Despite both schools being featured in several UAAP Finals matchups in other events like men's football, the now-dubbed "Battle of Katipunan" garnered nationwide attention for the first time in UAAP history when third-seeded University of the Philippines, after ending a 21-year long drought of Final Four appearance, overcame second-seeded Adamson University's twice-to-beat advantage to advance to the finals for the first time since their 1986 championship to face defending champions Ateneo de Manila University (who advanced first to the championship round after beating Far Eastern University in the semifinals) in men's basketball in 2018. Ateneo would eventually sweep UP in the best-of-3 finals series en route to their 10th (and 2nd consecutive) UAAP championship.
The rivalry between Ateneo de Manila University and De La Salle University, widely regarded as Philippines' foremost collegiate rivalry for decades, has resulted in sold-out games (especially in women's volleyball and men's basketball) that attract several public figures in attendance, including politicians, movie stars, and foreign diplomats. It is also the foremost school rivalry in the UAAP since La Salle joined the UAAP from the NCAA in 1986. However, the rivalry dates back to the time when both schools were playing in the National Collegiate Athletic Association from 1924 until the late 1977.
