Monasterio de San Millán de Suso

The Monasteries of San Millán de la Cogolla are a complex of two monasteries founded in the 6th (San Millán de Suso) and 11th centuries (San Millán de Yuso). The monasteries have changed owners many times (Visigoths, Spaniards, Muslims) and now bear their marks such as the Mozarabic arches inside the Suso building. Both buildings have been listed as UNESCO World Heritage Sites since 1997.

Work on this cathedral began in 1158 and was not completed in its current form until the 16th century. It contains several important works of art from the Hispano - Flemish style, as well as unique metalworks.

This cathedral is one of the icons of the city of Briones and is noted by its large baroque tower. The building is from the 16th century and is noted for its very tall features such as its naves and frescoes.
