San Millán de la Cogolla. Monasterio de Suso. UNESCO Heritage

Together with the Monasterio de Yuso in San Millán de la Cogolla, this Visigothic monastery was declared a World Heritage Site by the UNESCO in 1997; its caves were inhabited by a hermit saint in the 5th and 6th centuries. It was expanded in the Mozarabic and Romanesque periods; Benedictine monks arrived at the monastery in the 10th century. San Millán was a centre of political and cultural power in the Middle Ages and it was on its desk that the first words were written in Spanish in the 10th century as the Glosas Emilianenses, annotations to a Latin text.
