Gradac Monastery is a Serbian Orthodox nunnery south of Kraljevo in Serbia. It belongs to the buildings of the Raška school and resembles the Studenica monastery. The use of Gothic elements makes it the most Western-style religious building in Serbia, along with the Visoki Dečani Monastery.
Gradac was donated by Queen Hélène d'Anjou (1237-1314), wife of Stefan Uroš I. The monastery was built around 1275 and serves, among other things, as Queen Hélène's burial place.
Heavily damaged by the Turks after 1389, only fragments of the frescoes have survived. The building is characterized by Gothic elements of the windows and portals.
