Sigmundskron Castle
Sigmundskron Castle is a hilltop fortress on the south-western edge of Bolzano, first recorded in 945 as Formicaria. Duke Sigismund of Tyrol bought it around 1473, renamed it and rebuilt it to resist firearms. Since 2006 its ruins have housed the Messner Mountain Museum Firmian, Reinhold Messner's museum on people and mountains.
