Landesmuseum Hannover, State museum in Südstadt-Bult, Hannover, Germany

The Landesmuseum Hannover is Lower Saxony's state museum, a four-wing Neo-Renaissance building by Hubert Stier completed in 1902 on the edge of the Maschpark. Two main storeys rise over a high base around a large inner courtyard, with projecting central sections front and rear. A relief frieze, "Key Moments in the Evolution of Humanity", runs along the facade, carved by Georg Herting with Karl Gundelach and Georg Küsthardt.

The museum opened in 1856 as the Museum für Kunst und Wissenschaft in the Künstlerhaus on Sophienstraße, uniting the collections of three Hanoverian societies. The present four-wing building by Hubert Stier on the edge of the Maschpark was finished in 1902, with a relief frieze by Georg Herting, Karl Gundelach and Georg Küsthardt. Renamed the Landesmuseum in 1933, it became the Niedersächsisches Landesmuseum in 1950; an air raid on 8 October 1943 destroyed the dome above the central risalit and burnt out the second floor.

The name WeltenMuseum comes from the three "worlds" the collections are grouped into: NaturWelten, MenschenWelten and KunstWelten. The KunstWelten, reopened after rebuilding in 2025, hold the painting, print and sculpture collections from the Middle Ages to the early 20th century, joined by pieces of the coin collection. The ethnology department, one of the oldest in the German-speaking world, keeps around 20,000 objects from America, Africa, Oceania and Asia.

The building stands at the edge of the Maschpark, opposite the New Town Hall; the main entrance is reached by the wide staircase under the "DAS" banner. Inside, the three "worlds" — Nature, Humans and Art — are spread over two main floors around a large inner courtyard, so allow time to cross between wings. The art galleries reopened in 2025 after rebuilding.

The natural history section houses an iguanodon model that shows how scientific understanding of dinosaurs has changed over time. The model demonstrates how researchers have adjusted their reconstructions as new knowledge has emerged.
