La Paz, called Lobo, Llaunon or Ilawood, then Iznart after Gov. Manuel Iznart, was a newly established as a parish in 1868. In 1847, Fr. Candido Gonzales built a temporary church and convento of wood, bricks and tabique pampango. The present church was constructed from 1870-74. The church is a squat and less elegant version of the San Jose church in Iloilo.

Neoclassic features, and rustication stand in sharp contrast to the bricks used in the church. Two engaged columns supporting a triangular pediment bear the date 1970, apparently recent additions.
