Rosenburg Castle, Renaissance castle in Kamptal, Austria.

Schloss Rosenburg stands on a rocky outcrop above the Kamp Valley and blends medieval and Renaissance styles with 13 towers and ornate balconies. The fortifications and building sections come from different periods and shape the appearance of the entire complex.

A castle was first documented at the site in 1175; its Romanesque keep foundations survive. Count Kaspar von Rogendorf enlarged it in Gothic style in 1476, and the chapel and outer walls date from this phase. In 1487 the brothers Jakob and Christoph Grabner acquired it; their descendant Sebastian II Grabner had most of the Gothic castle demolished from 1593 to 1597 and rebuilt as a Renaissance palace with 13 towers.

The castle displays how nobility lived here, with furniture, weapons, and artworks from different periods arranged in its rooms. The furnishings tell the story of the people who inhabited these spaces and how they shaped their daily lives.

The castle stands on a cliff above the Kamp valley at 345 metres, inside the Naturpark Kamptal. The restored interior can be seen on guided tours; the tour includes a 19th-century collection of fossils and historic objects. A tavern on site serves visitors, and the open-air stage beside the castle has hosted theatre performances since 2004.

The tournament grounds laid out around 1614 were little used for medieval jousting; mock tournaments in historic costume are staged there today for visitors. The 1999 silver 500-schilling coin minted by the Austrian National Bank shows the castle with falcons and knights.
