Very cool place. Built in 1510 this monastery for nuns is still in use. This is the place that Saint Theresa lived. Beautiful grounds and interesting tour. Living history! Just outside of the incredible walled city of Avila. Do them a favor if you visit, buy a cheap trinkets from the gift shop. All handmade items by the nuns of the convent. The nuns have almost no contact with the outside world! Must see!
