Monasterio de San Juan de Duero

The most striking of Soria's sights, this wonderfully evocative and partially ruined cloister boasts exposed and gracefully interlaced arches, which artfully blend Mudéjar and Romanesque influences; no two capitals are the same. Inside the church, the carvings are worth a closer look for their intense iconography. It's on the riverbank, down the hill from the historic centre.
