Battle of Intramuros
The Battle of Intramuros may also refer to the "original" rivalry between University of the Philippines Manila (UP) and Ateneo de Manila in which first began on 1915 when UP and Ateneo played basketball games on Intramuros. Eventually the rivalry died down and was revived when both schools competed in the University Athletic Association of the Philippines and is now called the "Battle of Katipunan" from the avenue that connects Ateneo's new campus at Quezon City and University of the Philippines Diliman (The Manila university stopped sponsoring collegiate athletics after World War II.)
