[2][3] Built in several stages from the 17th to 19th centuries by the Dominicans, the best-preserved Pangasinan church bell tower and some parts have been reconstructed because of earthquakes.

Bishop Miguel Garcia de Nueva Segovia presided over the 1773 Synod of Calasiao at the sprawling Convento (per Manila Provincial Council Acts of 1771 to implement Decrees).

Calasiao had a new church of three naves (89 varas or yards long, 22 wide and 18 high with 2 rows of windows) with a bell tower.

[clarification needed] In 1945, the Lingayen cathedral and the archbishop's palace was temporarily transferred to Calasiao amid the miraculous 3 Liberation bombs thrown into the church and convent but failed to explode.

Luis B. Ungson reconstructed the church's and restored the bricked front wall, antique statues and the ceiling's original floral motif.

Its 5-storey octagonal brick bell tower (replica of the earthquake destroyed original on July 16, 1990) with architectural designs that slightly resemble those of the Southeast Asian Hindu-Buddhist Pagodas is 30 metres (98 ft) high.

The intricate sculpture has tone of the Renaissance age's European Art as demonstrated by the church ceiling or dome, walls and the altar from the aisle near the main door.

Outside, sculptures, could be found including the cave of the Nativity and the Sunico heritage bell on display and the Sacred Heart of Jesus.

In front of the church and Convento are parking areas for vehicles tightly guarded by a solid iron entrance gate.

[7] Some meters therefrom is the famous "Senor Divino Tesoro Shrine" with the miraculous statue of a crucified Jesus Christ (believed to grow in size).
