Wilanów Palace is Warsaw's answer to Versailles — a Baroque royal summer residence built for King Jan III Sobieski in the late 17th century. Unlike every other Warsaw palace, it survived World War II relatively unscathed and retains much of its original interior. The collection includes Italian paintings, royal apartments, a poster museum, and an impressive formal garden.
Getting there takes about 30 minutes by bus from the city centre. The gardens are as much a draw as the palace — beautifully laid out with fountains, sculpture, and a lake. The combined palace and garden ticket is worth it; the poster museum (Polish Poster Gallery) in the outbuildings holds a world-class collection of Communist-era graphic design.
