This was finished in 1797 and to-day stands the finest monument in the South-west of the epoch of the padres.

It is a really beautiful specimen of the Mexico-Spanish church architecture of that time.

No better testimony could there be of the indefatigable spiritual energy of the padres than this artistic structure standing now amidst a few adobe houses, and once completely abandoned to the elements.

Such a building should never be permitted to perish, and it well merits government protection.

Its striking contrast to Casa Grande, the massive relic of an unknown time, standing but a few leagues distant, will always render this region of exceptional interest to the artist, the archaeologist, and the general traveller.
From Bac, under the protection of the presidio of Tubac, some thirty miles farther south, later transferred (1776) to the present Tucson, Garces carried on his work.
