Roter Haubarg, Historical farm building in Witzwort, Germany

Roter Haubarg is a rectangular farmhouse in Witzwort with a red brick facade and a thatched roof. It stands on eight posts and reaches a ridge height of 17 meters, with 99 windows. The building is considered the best-known Haubarg.

The Adolfskoog was diked between 1575 and 1579 under Duke Adolf of Schleswig-Holstein-Gottorf, and a ducal building owned by Duchess Augusta stood on the warft in 1605. The often-cited construction date of 1647/48 for the present Haubarg has no documentary proof, though a 1679 map already shows it in its current form. The name "Roter Haubarg" first appears in a 1749 source concerning the farm's reclamation privileges.

The museum, run by the Museumsverband Nordfriesland, reopened in 2024 after a redesign as an audio installation. Every hour, four different twenty-minute audio plays feature the Haubarg, tools and rural everyday objects in conversation. A separate audioguide in the garden lets the voice of the Haubarg itself lead visitors between listening stations.

The building is open to the public and combines a restaurant in the former living rooms with a museum on Eiderstedt farming history. The museum, run by the Museumsverband Nordfriesland, reopened in 2024 as an audio installation: four different twenty-minute audio plays run hourly, and a separate audioguide leads through the garden.

During renovations in the 1980s, workers uncovered two buried cellars beneath the building. These discoveries suggest an earlier structure may have once occupied this same spot.
