The State Museum of Natural History Stuttgart, abbreviated SMNS, is one of the two state of Baden-Württemberg's natural history museums. Together with the State Museum of Natural History Karlsruhe it is one of the most important repositories for state-owned natural history collections.Exhibitions are shown in two buildings, both situated in the Rosenstein park in Stuttgart: the Löwentor Museum houses the paleontology and geology exhibitions, while the Museum Rosenstein in Rosenstein Palace focuses on biology and natural history. Every year, the SMNS is visited by about 110,000 people.HistoryPrior to World War II, the natural history collection of Baden-Württemberg was located at the Neckarstraße in downtown Stuttgart. A part of the exhibits were destroyed during the war, when the original building was destroyed by fire after Allied bombing. Luckily, most of the exhibits were sourced out and survived the war. Some specimens were also recovered form the rubble of the destroyed old museum building, including a spectacular plesiosaur today mounted in 3D in the Löwentor Museum exhibition.The biological specimens of the State's collection are displayed at the castle Rosenstein since 1954. For the paleontological collection, the construction of a new exhibition building began in 1981 and was finished in 1985.The principal exhibition area of Löwentor Museum consists of a single room, made up of three floors and over 3500 square meters (37'600 square feet) of exhibition area. The room has a height of up to 11 meters.
