With more than 5,000 different animals, fossils, and plants beneath its roofs, this museum is one of the city’s premier attractions. In addition to natural history, artwork from as early as the 12th century adorns the walls of further rooms. From religious artwork to still life, Italian masterpieces, and Dutch paintings from the 17th century, the art collection here should be on any enthusiast’s list. Expressionistic painter Alexej von Jawlensky’s work is also on display here, the painter spending the final 20 years of his life in Wiesbaden. There is something for everyone at this museum, with an impressive collection of rarities from across the globe collected under one roof.
