IUC is located in the vicinity of the Dubrovnik historical centre, at the address Don Frana Bulića 4.
The building, originally a school constructed in the first years of the 20th century, was offered in 1971 by City of Dubrovnik to the University of Zagreb for the needs of the IUC as well as other postgraduate studies programmes.
In December 1991 the building housing the IUC was shelled, burned down, and was completely destroyed by the ex-Yugoslav army. In October 1993, the IUC returned to the old address in the reconstructed and partly refurbished building, where it cohabitates with several programmes of the University of Zagreb. During the time, all building spaces have been reconstructed and put to use.
The building has a large conference hall which can accommodate 110 participants, 10 classrooms of different sizes (accommodating between 20 and 50 participants), a computer room and two cabinets. The conference hall and classrooms are air-conditioned, equipped with PowerPoint, overhead projectors and wi-fi. The building has available panels for poster session as well as equipment for simultaneous translation. Photocopying of work material and handouts can be arranged with the assistance of IUC Secretariat.
A central courtyard contributes to the atmosphere of the building since many social and academic gatherings take place there. The courtyard is also covered with wi-fi signal, so many participants replace the work in the classroom with the outside bench. Welcome receptions, coffee breaks, breakfasts, lunch and dinners are organised by Cafeteria Atrium.
Participants also have a possibility to be accommodated in the dormitory in the attic space or in the apartments on the second floor of the building. Accommodation is arranged separately at convenient prices.
