Beglik Tash is a prehistoric rock sanctuary situated on the southern Black Sea coast of Bulgaria, a few kilometers north of the city of Primorsko. It was re-used by the Thracian tribes in the Iron Age.
At the end of the 19th century, the Czech-Bulgarian historian and archaeologist Karel Škorpil produced the first scientific account of the sanctuary, which was then known as Apostol Tash. In 2002, Bulgarian archaeologists started excavations under the supervision of Tsonia Drazheva.
