Parish Church of Santo Domingo de Silos of Calatagan is a Registered Property, Province of Batangas located at Calatangan, Batangas, Region IV-A.
The town of Calatagan, a peninsula located at the southwestern-most tip of the province of Batangas, was formerly a part of the parish of Immaculada Conception in Balayan. In September of 1913, then Bishop Msgr. Jose Petrelli decided to separate it from the mother parish because of distance. The new parish of Calatagan adopted St. Dominic of Silos, an 11th century Benedictine monk, as its patron saint and celebrates its town fiesta on April 30.
The private chapel of the Hacienda Calatagan, which was owned by the Roxas de Ayala family, was donated to the parish and after the addition of some improvements served as its Parish Church. Through the years, renovations have been done on the building – among others are the removal of the bell tower to expand the church interior, the addition of wings on both sides, the expansion of the sacristy, the construction of a Blessed Sacrament chapel, and the installation of a wooden statue of Sto. Domingo de Silos in the niche above.
