Pinaglabanan Shrine was built in 1976 to commemorate the 1896 Battle of Pinaglabanan in the city, then known as the town of San Juan del Monte.[2] The battle was part of a campaign by Katipunan revolutionaries, led by Andrés Bonifacio, who intended to seize El Deposito, an underground reservoir supplying water to Intramuros, and El Polvorín (the gunpowder depot). Though successful in seizing El Polvorín, the revolutionaries lost the battle, and were unable to reach El Deposito.[3]
The centrepiece of the shrine is the Spirit of Pinaglabanan, a brass sculpture by Eduardo Castrillo that features three figures atop a semicircular base.[3] The National Historical Commission of the Philippines runs two museums within the park, the Museo ng Katipunan (Museum of the pinaglalaban) and the Museo El Deposito (El Deposito Museum). The Spanish-era El Deposito underground reservoir beneath street level has since been restored and is also open to the public.[4]
