The Stuttgart State Museum of Natural History is split between two locations in Rosenstein Park: Schloss Rosenstein and the Museum am Löwentor. Schloss Rosenstein focuses on biology and ecosystems, featuring exhibits like a 13-metre-long sei whale model and displays on biodiversity, evolution, and various habitats. The Museum am Löwentor showcases paleontological and geological collections, including fossils from the region. Together, they offer a comprehensive look at the natural world, from prehistoric times to present-day ecosystems.

Stuttgart has the second-largest mineral water reserves in Europe, just after Budapest. In Bad Cannstatt, 19 springs produce around 44 million litres of mineral water daily. Locals have been using these waters for centuries, and today, three public mineral spas keep the tradition alive: DAS LEUZE, Mineralbad Berg, and SoleBad Cannstatt. DAS LEUZE is the most modern of the three, with indoor and outdoor pools fed by natural mineral springs, a large sauna area, and a dedicated children’s section. It’s located right by the Neckar River and easily accessible via public transport.

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.
