[1][2] The city of San Carlos was once a small Negrito community area named Nabingkalan.
Manuel Gomara wanted no more delay in the construction of the church and so in May 1935, he sought the help of the hacenderos of San Carlos: the Gamboas, Broces, Llantadas, and the Menchacas.
Don Julio Ledesma eventually donated ₱20,000 for the construction project after the initial ₱12,000 budget was deemed insufficient.
Dr. Cerada drew the blueprint of the church, and its construction was supervised by architect Angel Locsin Yulo.
The finished church was consecrated and inaugurated on Saint Charles Borromeo's feast day in 1935.
