La Iglesia de Cosío es una construcción del siglo XVII reedificada a principios del XIX, pero todo parece indicar que ya en el siglo XIII existía una iglesia en este mismo lugar, sobre la cual se reedificaron al menos dos templos, uno ya existente en el siglo XVII y otro reedificado a principios del XIX. Del edificio original gótico no se conserva nada, sin embargo, del edificio del XVII aún se conserva el ábside tal cual debió ser con sus bóvedas, sus contrafuertes de piedra y demás.

The Church of Cosío is a construction of the seventeenth century rebuilt at the beginning of the nineteenth, but it seems that already in the thirteenth century there was a church in this same place, on which were rebuilt at least two temples, one already existing in the century XVII and another rebuilt at the beginning of the XIX. Of the original Gothic building nothing is conserved, however, of the building of the XVII the apse is still conserved as it should have been with its vaults, its stone buttresses and others.
