This cave is a subterranean network of caverns extending more than a kilometer deep. The Katipunero Revolutionaries during the war against Spain used it as a camp in 1896 and again during the Filipino-American War in 1898 as hideout of General Emilio Aguinaldo (the First President of the Philippines). It was also used as a sanctuary by the Japanese Imperial Army when the Philippines was liberated by joint Filipino and American Forces.
