Once almost in ruins, Lucerne Abbey was reconstructed in spectacular fashion. Admire the 12C façade, the Romanesque doorway and the nave recalling the Cistercian style. Inside, the chancel is amazingly bright and lofty. Note the Gothic bell tower resting on the transept, which houses an 18C organ. On your way out, visit the former refectory and its 12C "lavatorium" (ablutions fountain), the halls of justice - now devoted to exhibitions - and the dovecote with 1 500 holes. The remains of an aqueduct (1803) can be seen in the park.
