The "Muzeum vychodnich Cech," or Museum of Eastern Bohemia, is as well known for its cubist architecture as for what's in it (although it is a decent museum for the area). It was designed by Jan Kotera (a common misconception, formerly held by me, was that it was designed by Josef Gocar, who designed some of the older suburbs), and completed in 1912. The exhibits are mostly historical in nature, stretching from the Stone Age to the mid-20th Century.
