This Alpine system of fortifications that today appears like a bizarre work of art, is open to rediscovery. Of special interest, is Bunker No. 20 at Curon/Graun, near the source of the Adige River. This is the barrier at Plamort, in a swampland above the village of Resia/Reschen and is designated as a natural monument. Guided tours are conducted all year round and must be arranged in advance with the Tourism Office, by telephone: 0473 633101.
