Piazza Gries, with the architectural complex of the Abbey of Benedettini di Muri-Gries on the right handside, is right in the middle of the quarter. The monastery, initially hosting Agostinian monks (1406), was damaged by peasant revolts in 1525 and destroyed during the Napoleonic wars. It was suppressed by the Bavarian government in 1807 and donated by the Austrian Emperor to Benedectine Muri Monks (Switzerland) in 1845. The oldest centre is the castle, built by the Morit-Greifenstein Counts in 1200, and whose original 'mastio' (tower) today is the church's bell tower. It hosts one of the heaviest bells in Alto Adige (5,026 kg).
