Municipal House (Obecni Dum): has been fully restored to its former beauty after many years of neglect. It is a prime example of Art Nouveau in Prague and has seen contributions by most of the major Czech artists that were around during its construction in the 20th century. The most striking feature on the outside of the building is the mosaic by Karel Spillar, although this is completely overshadowed by the decor of the interior.

The Mayor Hall features murals by the famous Czech artist Alfons Mucha, while Smetana Hall is home to the Prague Symphony. Guided tours are recommended, as you get to see many rooms that aren’t normally open to the public.
