A 4D Virtual Presentation of the White Bastion Fortress in Sarajevo

Selma Rizvič

ABSTRACT

The fortress known as the White Bastion is one of the most impressive and important historical sites in Sarajevo in Bosnia and Herzegovina. It is located on the southeast outskirts of the city and offers a view on the city valley. Throughout history it has occupied a significant strategic position. The fortification is a part of the dominant defensive walls that once surrounded the old city of Vratnik.

Various strata, starting from the medieval to the present contribute to the significance of this historical site. During the archaeological excavations the remains of medieval fortification from the 14th century were found, as well as those from the Ottoman period (17th century) when the fort was expanded to accommodate some new structures. During the Austro-Hungarian rule, part of the fortification and the structures inside the walls were demolished and replaced.  During the early excavation, a significant number of artefacts was found, recorded and conserved prior to their display at the Museum of Sarajevo.

The 4D Virtual presentation of the White Bastion aims to present the historical development of this cultural heritage site through digital stories combined with interactive 3D models of the Bastion in various periods. These models consist of digitised findings from the site and their 3D reconstructions.
