In 2019 we are celebrating the 400th anniversary of the completion of the expansion of the Royal Castle in Warsaw which was initiated by Sigismund III Vasa. As a result of it, the new royal residence became the focal point of the political, cultural and court life of the Polish-Lithuanian Commonwealth for the following decades. This anniversary presents a special opportunity to celebrate the dynasty and the time in which it ruled. Twelve rooms, containing nearly 300 exhibits on loan from 77 institutions, sophisticated scenography, a film with a digital reconstruction of the Castle of the Vasas – all this in the most important and largest exhibition in the Year of the Vasas.
