Here are several of the heritage / ancestral houses in Malolos City, Bulacan.

Alberta Uitangcoy-Santos House (also Museo ng Kababaihan ng Malolos)
Built in 1914 (replacement of an earlier house destroyed by fire). It is most well known for its connection to the Women of Malolos, a group of young women (mestizo / sangley background) who in 1888 petitioned the Spanish Governor-General to allow them to study Spanish.
