Museum Island (Museuminsel)
the river Spree divides Mitte into North and South sections and in the middle of it is the grandiose Museum Island, holding about 20 galleries and museums that will definitely leave you reeling. Do some research before going and decide which ones you want to see most. Each has admission fees (except for special days such as Lange Nacht der Museen and the first Sunday of every month, when entry is free) so plan how much you want to spend. Highlights are the Pergamonmuseum, the Altes Museum (Old Museum) and the Museum of photography.
