The National Museum has a number of buildings that are home to 14 million different items from the natural history, history, arts and music departments to name a few.
Founded in April 1818, the National Museum now encompasses the Museum of Natural Science, the Historical Museum, the Naprstek Museum of Asia, African, and American Cultures, the National Museum Library, the Central Office of Museology and the Museum of Czech Music, which are spread out over the city.
If you're a literature fan, the Franz Kafka Museum is also worth a visit. The small museum is home to a number of Kafka's first edition books as well as letters, diaries and drawings created by the author, who is best known for penning 'The Metamorphosis'.
Moving onto the more unusual of the museums, The Museum of Alchemists and Magicians of Old Prague is just 10 minutes away from the Kafka Museum. Here, you can wander through the exhibits as you glance at the wonders of emperor Rudolf's alchemists. See the wisdom texts of the alchemists and climb the "spiral of life up to the sky", a spiral staircase built in the 16th century.
However, probably the most bizarre museum in Prague is the Sex Machines Museum, which exhibits around 300 sex gadgets, some of which date back as early as the 16th century. At the museum, there is a little theatre that shows some of the world's earliest pornographic films from the 1920s.
