The church is considered as the best-preserved church complex in Pangasinan province. The bell tower and some parts of the church were recently reconstructed, having been damaged by an earthquake. Despite natural calamities the church is well conserved and the recent work has not deviated from its original appearance.
The sprawling convento or convent – the site of the 18th century Synod of Calasiao – has an excellent example of a separate kitchen structure. The retablo mayor (major altar) is massive and its complex woodwork may be seen at the back.
Long live Calasiao Church!
