The Mosteiro de Santa Cristina sits on a promontory above the Sil, reached by a trail through chestnut and oak forest that descends from the rim road. The church is Romanesque, built in the 12th century, with a carved apse that contains some of the most sophisticated stone carving in Galicia — hunting scenes, musicians, and fantastical beasts running around the corbels above the east end.
The monastery is best approached on foot from the road above, a descent of about 40 minutes through dense forest. The reward is the building standing alone in the trees, with the river far below and the terraced vineyards visible on the opposite bank. It is possible to see the church interior; opening times vary and it is sometimes closed, but the exterior and setting justify the walk regardless.
