The European University Center for Peace Studies (EPU) is situated in Stadtschlaining, the second smallest town of Austria, in the Austrian province of Burgenland. It is located 120 km south of Vienna, 100 km north of Graz and is just half an hour by car from the nearest town in Hungary, Szombathely. It is embedded in a beautiful, hilly countryside and offers possibilities for recreation like walking and riding bicycles.

Stadtschlaining and its facilities frequently serve as the venue for meetings of international organizations, such as the UN, UNESCO, or the Organization for Security and Cooperation in Europe (OSCE).

Stadtschlaining has also hosted a number of high-level peace negotiations related to conflicts in Bosnia, East Timor and Sri Lanka. The 13th century castle, where the administrative offices of the EPU and the Schlaining Peace Center are based, is a beautifully preserved fortress which has been restored with modern facilities providing also conference space and a café. A major part of the castle houses the European Peace Museum with its permanent and special exhibitions. Most of the courses of the EPU are organized in the seminar rooms of Haus International, the EPU student residence.

Accommodation for EPU students is provided at the student hotel "Haus International". The Peace Library situated in the town’s former synagogue, has an extensive collection of books, magazines and newspapers related to peace research and international politics. It is also accessible through the Peace Library Online Catalogue.
