the old municipal hall was built by the demetrio ledesma, who was the "presidente municipal" of jaro which was then a separate administrative unit from iloilo city. in 1933, the building was under construction and was completed in 1934. in 1937, jaro along with four other towns was absorbed by iloilo city which meant that the building no longer functions as a municipal hall. it was then used as the headquarters of jaro's police and the jaro health center and jaro fire station would be built besides the building.
