Stećak

Stećak (Стећак, ; plural: Stećci, Стећци, ) are monumental tombstones made in medieval Bosnia. 
History.
The Stecci are relared to the Vlachs who lived in the Dinaric Alps of Herzegovina since the Middle Ages. Most of the Stecci were created after the X century and until the Turk invasion of the Balkans. According to the scholar Wenzel the Stecci are the clear evidence of the existence of a romance territory in the area between Italy and Romania, that now has disappeared.
