The mission, located on the Tohono O'odham reservation, has been undergoing a restoration for a couple years now. It's recognized as one of the best examples in the U.S. of mission architecture. On this day, 30 Nov 2007, you can see quite a bit of work remains to be done. It's open to the public daily and is actively used.
I'll return here with a new photo once the scaffolding is all down in March. There'll be a two month window to photograph the mission before scaffolding goes up on the east side to begin the final restoration work.
