The old mills in Bulla, right above Ortisei, were built in the 8th and 19th century. The Zaramin mill is abandoned, but the Rumanon mill was restored in 1999 and the Droch mill in 2010. They are now fully operational. Visitors can join a guided tour and learn more about the mills and the ancient local lifestyle. More information is available at the Tourist Office in Ortisei.
