Naturkundemuseum Ostbayern, Natural history museum in Herzogspark, Regensburg, Germany.

The Naturkundemuseum Ostbayern has occupied the classicist Württembergisches Palais, also called Herzogspalais, on the edge of the Herzogspark in the northwest of Regensburg's old town since 1961. The palace was built in 1804 by court councillor Georg Friedrich Ritter von Müller to plans by Emanuel Herigoyen, executed by building director Joseph Sorg. The displays centre on the geological formation of eastern Bavaria, with a natural history cabinet holding a wooden library from 1790, numerous mounted animals and a few live small animals and bees.

The museum moved into the classical Württemberg Palace in 1961, combining natural science collections with the preservation of a historic building. The collections themselves span decades and document the natural history of the region.

The museum displays a reconstructed historical natural science cabinet with its original wooden library from the 18th century. Visitors can see how naturalists of that era organized and presented their collections.

The building is located in Herzogspark and is easy to reach on foot, with a park surrounding it where you can walk before or after your visit. It helps to check the current opening hours in advance, as times vary depending on the season.

The museum keeps a few live small animals and bees alongside its mounted specimens, and the adjoining Herzogspark holds a pond and a geological teaching trail. The collection grew from a late 18th-century cabinet and was rebuilt from 1947 after bombing destroyed it in 1943.
