Deemed as a national cultural treasure by the National Museum of the Philippines and the National Commission for Culture and Arts (NCCA), the Sts. Peter and Paul Parish Church is the second oldest church in Pangasinan, having been built between the 17th and 19th centuries by the Dominicans. Its structure is reminiscent of Baroque designs and it features original retablos (devotional paintings) within. A preserved bell tower is also a point of interest, as well as the intricate paintings across the ceilings.
