Menhir (from Breton, men - stone, hir - long, tall) "Chuchul kamak" (stone) is located in the western part of the Sakar mountain, in the lands of village of Ovcharovo (Harmanli Municipality). Since 2008 the menhir is fenced and has a informative plate where is written that this is the only menhir in Bulgaria and Southeastern Europe.
