The " Nature House " is, first of all, a very fine museum which, in a modern way, shows, throughout its 90 rooms, almost everything that you would wish to know about the natural environment of this region and elsewhere. Highlights of the tour are Man's links with Nature, which are underlined, notably by reminders of animal myths and legends. Saurians, the sea world, space and crystals (of which the Alps have a plentiful supply).
