This is a two-storey treasure chest of some of Spain's most imaginative Romanesque art. Although the overall effect is spectacular, the sculpted capitals are especially exquisite, with lions intermingled with floral and geometrical motifs betraying the never-distant influence of Islamic art in Spain. The guided tour covers the 17th-century botica (pharmacy) and a small museum containing religious artworks, Flemish tapestries and the odd medieval sarcophagus. Guided tours are in Spanish only, and other visitors are usually allowed to wander more freely.
Don't miss the unusually twisted column on the western side. The pieces executed on the corner pillars represent episodes from the life of Christ, while the galleries are covered by Mudéjar ceilings from the 14th century. In the northeastern corner sits a 13th-century image of the Virgin Mary carved in stone, and nearby is the original burial spot of Santo Domingo. Note that much of the monastery is off limits to visitors.
