The impressive castle stands above Ponte Gardena/Waidbruck, above the gateway to the Val Gardena/Gröden. Interesting interior, partly with original furniture. An exhibition shows the life of Oswald von Wolkenstein. The old fortress (formerly used to raise duties) of Duke Sigismunds "the Coin-Rich" is located on the other side of the Valle Isarco/Eisacktal, in the village of Colma/Kollmann. The two fortresses are supposedly connected to each other by a subterranean passageway. Whenever the lords of the castle were in danger, they could escape to safety in Colma via this underground passage. Worth seeing are also the library, among the most famous ones of its time, the hall of knights, the dining hall and several other rooms and halls decorated with precious furniture and paintings.
