St. Vincent Ferrer Chuch is one of the biggest and oldest unreinforced brick churches (18th century) in the Cagayan Valley. The church has all the requisites of an Old Spanish brick church like wooden altar, columns and lattices and a museum which houses centuries old church artifacts. Other well-preserved Spanish monuments include a Spanish Flagpole and Dampol Bridge – an unreinforced bridge made of bricks. In the 1960’s, after being christianized, the Ilongots gave up their head-hunting ways and started to call themselves Bugkalots in order to bury their bloody but proud past. The Isinais, formerly called Mallats or Imaalats were gentle and easily embraced Christianity. The church, declared by the National Museum as a National Cultural Treasure is a forty-five minute drive from Bayombong.
