While visiting warsaw, we made sure to stop and tour the Wilanow palace. There was beautiful art and statues inside and it was fun to learn the history of the people who lived there. It's amazing that this palace survived both world wars which is a reason why the palace is one of Poland's most important monuments. 

You can tour the gardens around the palace (which we didn't do) but we peeked out the windows to see parts of it. The gardens were beautiful from what I could see!
