Making Ourense and Lugo a single kingdom, the waters of the Rivers Sil and Miño flow and then create a divine environment, the Ribeira Sacra. A place touched by Heaven. Stunning scenery such as the canyons of the River Sil – which are navigable – and landscapes that are home to one of the largest concentrations of churches and monasteries in Europe. Some are as impressive as that of Santo Estevo de Ribas de Sil, built on a hillside and surrounded by lush forests. Or that of Montederramo, of colossal dimensions. Or that of Ferreira de Pantón, inhabited by nuns beginning in the 12th century. Or, excavated from the rock, San Pedro de Rocas, the oldest in Galicia.
