Belvedere Palace was originally the home of Prince Eugene of Savoy (1663-1736). This is now an art gallery for 19th and 20th century art and houses the famous painting by Klimt, "The Kiss", which is much more amazing to see in person. It has other paintings by him (like "Judith"), and also has some Van Gogh, Manet, Monet and others.

The Rathaus with skating rinks set up in front.

Schloss Schoenbrunn is the summer residence of the Hapsburgs and has 1,441 rooms. The girls (tuckered out from the zoo experience), gracefully slept in the stroller while I got to listen to the LONG (not 1400 rooms long...you only get to see 40 rooms) audio tour and visit the palace.
