The sleepy but picturesque city of Olomouc, Czech Republic, is in Moravia a few hours east of Prague. Good luck finding another tourist! It has two beautiful town squares and, like Prague, a fascinating astronomical clock re-built after World War II in a politically-correct socialist theme.

Olomouc also has a nice old cathedral not far from the center of town.
The beautiful Tritons fountain is close to the cathedral:
