Amsterdam is a city of museums – there are more than 400 museums and art
 galleries within the city. It is said that no other city in the world 
has more museums than Amsterdam. Obviously, museums are among the main 
tourist attractions. The Rijksmuseum, Van Gogh Museum, Anne Frank House 
and the Stedelijk Museum are the most popular choices, but there are 
many interesting smaller museums. There are museums on coffee, 
spectacles, pianos, diamonds, cheese, beers, and many more. Here are the most bizarre ones.
