King Casimir the Great built a vast Gothic castle here in the mid-14th century; he often visited and organized hunting escapades to the nearby Niepołomice Forest.
At the same time the settlement of Niepołomice was established, which performed service functions for the court and the castle. The work of the King was continued by his successors: Władysław Jagiełło, Sigismund I the Old and Sigismund II Augustus, who gave the castle its current shape of a square with an inner courtyard.
From the 17th century, the castle fell into decline, and after partition, the Austrians turned it into barracks. In the interwar period, it was used as a public facility; ten years ago it was taken over the municipality of Niepołomice. After a thorough renovation, this former royal residence was restored to its former glory.
Currently, it houses the "Royal Palace" hotel, with luxurious rooms for more than 50 people, and the Conference Centre. In addition, it houses also the "Castle" Cultural Centre, which organizes many cultural events: recitals, concerts, performances, knight shows and exhibitions. The chambers of the castle house the Niepołomice Museum, featuring hunting exhibits.
