"The El Deposito was an old underground water reservoir in San Juan del Monte, now the city of San Juan in Metro Manila, Philippines. It was built by the Spanish authorities in 1880 with a capacity of 15 million gallons to provide the residents of Manila and its surrounding areas with an adequate water supply. The reservoir was historically known as the site where the onset of the Philippine Revolution through the Battle of San Juan del Monte took place in 1896.
On August 30, 1972, a marker was installed by the National Historical Commission of the Philippines in recognition of the old reservoir as a cultural property. In commemoration of the first battle of the Philippine Revolution, the land along El Deposito was converted into a recreational park named the Pinaglabanan Memorial Shrine and Park." -
