The first of unknown origin, was in April, 1869 and it was reconstructed in 1892 but was burned again for the second time in 1896 when the school was used as quarters and barracks of the “Voluntarios Locales de Bacolor” (native soldiers under the Spanish Army) who were the first to revolt against the Spain. The third fire caused by the explosions of shells occurred in 1898. The school then was made as Maestranza (ordinance in the manufacture of bullets and cannon balls) by the Amobilizadores (native soldiers of Spanish Government).
