The Palace and Gardens are a reasonably interesting half day trip from Olomouc. The Palace is just off of the main square and there are regular tours. The interior is pretty a standard European palace, though the library was nice. I spent an inordinate amount of time looking at the two impressive Coronelli globes, which were the highlight for me.

If you would like a preview of what to expect from the interior this palace was used extensively for the interior scenes of the film Amadeus.

There is an English garden behind the palace which was reasonably nice. A little further out, about a 10 minute walk, are the more formal flower gardens. These were a little more interesting and the Rotunda and colonnade were nice accompaniments to the flower beds.

The train station is a little way from the centre but it is a fairly simple walk to the the attractions.

Overall I wouldn't recommend travelling a long way to see this site, however if you have a half day spare whilst in the area it is a fairly worthwhile trip, but if your time in Moravia is limited I would recommend spending more time wandering aimlessly in the parks and cobbled streets of Olomouc.
