Red House, Cultural heritage monument in Mitteldorf, Vaduz, Liechtenstein.

The Red House is a heritage monument in Mitteldorf, Vaduz, displaying its characteristic dark red exterior that has been maintained since the 19th century. Its structure is defined by ornate gabled stairs and a substantial tower containing residential spaces.

The building's origins trace back to 1338, establishing its deep historical roots. In the early 1900s, the artist and architect Egon Rheinberger oversaw major expansions that shaped its current form.

The name comes from the dark red paint on the stepped-gable house, documented since at least the mid-19th century. After 1807 the Rheinberger family used the building for Holy Mass and as a place of study; the altar and other objects from that chapel are now held by the Liechtenstein National Museum. A fresco on the east side of the tower recalls the legend of Josef Litscher.

The site is located centrally in Vaduz and can be viewed from multiple angles without interior access. The location is easily reached on foot and offers several perspectives of the exterior.

The connecting tower was designed by Egon Rheinberger himself and built between 1902 and 1905, joining the previously free-standing house and the Torkel building. On the tower's east side, a fresco recalls the legend of Josef Litscher, who is said to have murdered his brother and fled to the St. Johann monastery.
