The best known, and certainly the most valuable monuments of medieval art in Bosnia and Herzegovina are the Stećaks. Stećaks are monumental gravestones, usually stone monoliths of varying shapes and sizes. There are about 60.000 tombstones organized in large necropolis all over Bosnia and Herzegovina. The Stećak necropolises are a mysterious aspect of Bosnian and Herzegovinian history. The most intriguing are their origins, whom they belonged, who was buried under them, as well as engraved symbols, and mystic messages on them. These engravings inform us of social differences of those that were buried under them, but also of religious differences. Digital Catalogue of Stecaks is an interactive digital catalog in the form of schematic description of the exhibitions.
