Stećak is the name for monumental medieval tombstones, that lie scattered across Bosnia and Herzegovina, and the border parts of Croatia, Montenegro and Serbia. An estimated 60,000 are found within the borders of modern Bosnia and Herzegovina and the rest of 10,000 are found in what are today Croatia (4,400), Montenegro (3,500), and Serbia (2,100), at more than 3,300 odd sites with over 90% in poor condition. They are cut in a variety of recognizable stećak forms, with certain percentage being richly decorated and some individual stećci also containing inscriptions in form of epitaphs.

A headstone, tombstone, or gravestone is a stele or marker, usually stone, that is placed over a grave. It is traditional for burials in the Christian, Jewish, and Muslim religions, among others. In most cases, it has the deceased's name, date of birth, and date of death inscribed on it, along with a personal message, or prayer, but may contain pieces of funerary art, especially details in stone relief. In many parts of Europe, insetting a photograph of the deceased in a frame is very common.
