The Stuttgart State Gallery (Staatsgalerie Stuttgart) is one of Germany’s leading art museums, showcasing works from the 14th century to the present. Its collection includes approximately 5,500 paintings and sculptures, 250,000 works on paper, and up to 250,000 archival documents from artists' estates. The museum comprises three main buildings: the original 1843 structure, the postmodern extension designed by James Stirling in 1984, and a 2002 addition by architects Wilfrid and Katharina Steib. Stirling’s extension, known as the Neue Staatsgalerie, is celebrated for its innovative design that integrates a public walkway through the museum, blending classical and modern elements. The Staatsgalerie's extensive collection features masterpieces by artists such as Oskar Schlemmer, Henri Matisse, Salvador Dalí, and Joan Miró.

This museum is a goldmine for all those who are interested in the history of both the state and the city: while the permanent exhibition '750 years of Hannover' display the changes down the centuries, the 'History of the City' section traces back the development from a medieval town to a sizable city. The third department informs about the rural life between the 17th and the 20th century while temporary exhibitions feature different themes and numerous events.

The museum showcases an extensive collection spanning from the Prehistoric to Hellenistic eras, featuring bronze and marble statues, funeral offerings, ancient coins, clay pottery, golden jewellery, and fragments from ancient temples. Among the notable exhibits is the awe-inspiring Medusa pediment from the temple of Artemis, dating back to 585 BC. Additionally, visitors can marvel at the stone lion of Menecrates, a likely funeral offering to the renowned politician, a limestone pediment from the temple of Dionysus, 13 identical small statues of goddess Artemis, and a marble torso of Apollo.
