One of the first buildings you come across at Ranchos de las Golondrinas is the church. The church is the north building of a hacienda that has a central plaza with a well in the center and hornos for baking. Note the church has a pitched, tin roof, but the other buildings have flat roofs. The church originally had a flat roof as well, and the tin roof would have been added after 1850 when New Mexico became a US territory which opened up trade and goods to come in from the Eastern US. The ceiling of the church still has the horizontal vigas (timbers) that supported the original flat, dirt roof.

The interior of the church has simple benches for pews, an artisan crafted retablo at the altar, and hand carved Stations of the Cross (the Stations of the Cross are a modern addition, according to a docent).
