Closed for renovations until at least autumn of 2023.

Housed inside the Wilanów Palace’s former indoor riding area, the Poster Museum features two large halls full of wonderful posters from all over the world. At almost 60,000 pieces, this is reportedly the largest poster collection to be found anywhere. The museum focuses on the artistic merits of the posters rather than their documentary value and plays host to a cycle of temporary events and exhibitions. As a contrast to the historic palace and collection of paintings next door, this makes for interesting additional place to visit while in Wilanów.
