Palais Niederösterreich

Palais Niederösterreich, historically known as the Niederösterreichisches Landeshaus (Estates House of Lower Austria), is a historical building in Vienna.

The building housed the estates general of the state of Lower Austria until 1848.

In the revolution of March 1848, the Niederösterreichisches Landeshaus played an important role as the focal point of the revolutionary forces.

In 1918 it was the seat of the parliament of the new Republic of German Austria.

After the legislature and the ministries moved out of the building in 1997, the building underwent substantial renovations and restoration work, and is now used for exhibitions and for private functions and events.
