Santa Rosa de Corodéguachi - Alias Fronteras
The ruins of the Presidio of Santa Rosa de Corodéguachi, commonly called "Fronteras" can be visited today by crossing the international border at Douglas, Arizona / Agua Prieta, Sonora and proceeding south to the town of Fronteras. The ruins are at the point of the hill on the west side of town past the town hall.
