Jaro Plaza was designed by Father Juan Aguado, with construction overseen by Demetrio Ledesma, who later became Presidente Municipal.

In the 2020s, a comprehensive beautification and restoration project was launched for Jaro Plaza, with a budget of P20 million.

Known as the "Heroine of Jaro," Patrocinio Gamboa played a pivotal role in delivering the Philippine flag, the first outside of Luzon, to the Santa Barbara headquarters of General Martin Delgado, just in time for the revolutionary government's inauguration.

It also commemorates the friendship between Lopez Jaena and General Martin Delgado, who were both students at the nearby San Vicente de Ferrer Seminary and were known to frequent the plaza during their youth.
