Kaiserhaus, Historical museum in Baden, Austria.

The Kaiserhaus at Hauptplatz 17 is a three-storey building with an early classicist (late Josephinian) facade: a banded ground floor, a rectangular portal flanked by columns, and above it a balcony whose straight window and door hoods rest on volute consoles. The second upper floor is slightly lower. In the rear part of the property, by the garden wall, stands a polygonal pavilion with arched doors under a curved roof topped by a crescent symbol.

Emperor Franz I acquired the building in 1813 as an imperial residence and used it until 1834. The property was originally owned by Prince Nikolaus II Esterházy before the Imperial Treasury took it over.

The name Kaiserhaus recalls the building's use as Emperor Franz I's Baden residence from 1813 to 1834 and, from January 1917, as the seat of the Army High Command under Karl I. The court moved here from Laxenburg's Blauer Hof on 6 February 1918 and stayed until 1 July 1918. Since October 2013 the house has served as a museum, opened with Gerhard Tötschinger's exhibition "Die Welt der Habsburger" showing figurines by Helmut Krauhs.

The Kaiserhaus stands at Hauptplatz 17, its entrance marked by a column-flanked portal with a balcony above. The building has housed a museum since October 2013, after exterior and interior renovation from 2012. The rear garden wall holds the polygonal pavilion, reached through the courtyard.

A polygonal pavilion from the early 19th century is part of the property and features painted walls. These wall paintings create the visual illusion of being inside a tent.
