Norway
For anyone who's interested in architecture, art or design, this is a must-see. Dating from 1930-1950s, it looks a little austere from the outside, but the interiors are stunning - with a multitude of different rooms decorated with murals, mosaics, frescos, tapestries and sculpture. Free to visit in winter, in summer there is a small admission charge.
