History of Los Banos

Mainit was a barrio of Bay until 1589. In 1595, a temporary building made of bamboo and cogon was built to serve as shelter for the patients who journeyed to Mainit to seek cures for their ailments. The early traders from Las Pinas such as the "Eusebio clan" and from Manila the "Lopez clan" are considered the earliest to have established farming and business establishment in the area followed by the Kalaw, Palakpak, Bernardo, Clemente and De Castro
