## About

Santa María la Mayor is the least visited of the four Argentine World Heritage missions, and therefore one of the quietest. Its church was never finished; walls, the school and part of the town layout survive.
It is near Concepción de la Sierra in southern Misiones and can be combined with Apóstoles and the Yerba Mate Route.

**Local tip:** If you are doing the Yerba Mate Route, it is on the way between Apóstoles and the Uruguay River.
