Time has had its way with this Gothic cathedral without a rooftop, a hauntingly beautiful sight well worth a detour. The church was built in the 13th century by Cistercian monks, who designed it after churches built by their order in France. But starting in the 15th century it fell into ruin, declining gradually over centuries. Grass has grown through the floor, and the roof and windows are gone. What's left of its facade and walls makes a grandiose and desolate picture. In July and August the scene is enlivened by evening concerts arranged by the Accademia Musicale Chigiana in Siena. Contact the tourist information office at the abbey for details.
