Normannenhaus, Neo-Romanesque event venue in Jena, Germany

Normannenhaus is a Neo-Romanesque building in Jena featuring four large halls. The spaces have ceilings reaching seven meters high and combine historical architecture with modern equipment such as audio systems, daylight projectors, and LED lighting.

The Mannheim architect Georg Ludwig Freed designed the house for the Akademische Turnerschaft Normannia, a fraternity that began as the Pharmazeutisch-Naturwissenschaftlicher Verein and took its name in 1885. Construction started in 1897 and the house was inaugurated on 30 July 1898. The Nazis banned the fraternity in 1938 and expropriated the building; in 1945 the Soviet military administration confiscated it and transferred it to Friedrich Schiller University. After 1947 the university altered the layout and bricked up the festival hall's original stained-glass windows.

The name comes from the Akademische Turnerschaft Normannia, a student association that began as the Pharmazeutisch-Naturwissenschaftlicher Verein Jena, became Pharmazia, and took the name Normannia in 1885. Its members included Georg Sattler and Ernst Sarfert. After 1945 the house passed to Friedrich-Schiller-Universität and was later used by the Christengemeinschaft, a kindergarten, the Institut für Dialektischen Materialismus, a youth club and the Jenaer Philharmonie.

The building stands in Jena's city centre, not on a hillside. The 2017 restoration used surviving plans from the Worms city archive to recreate the original state of house and garden, so the grounds are part of the visit. The ground-floor Kneipzimmer held 44 people and could be enlarged; the first-floor Festsaal seated more than 100.

The 1897 plans survive with samples of the original stair shavings and wallpaper patterns such as Linkrusta, and the 2017 restoration worked from building files kept in the Worms city archive. Detail drawings cover the east balcony railing, the zinc profiles of the flagpole and the removable glass partition between the two Kneipzimmer.
