Overlook the uninspired name of this building and pay a visit to discover different aspects of ‘older’ Czech and natural history. The museum does excellent kid-friendly exhibitions too. The building itself can be considered an eyesore – before its role as a museum, it was originally the Prague Stock Exchange (1938 to the arrival of occupational forces), then Parliament (1946-1992) and finally from 1995-2009, the headquarters of Radio Free Europe.
