Pobiti Kamani (Bulgarian: Побити камъни) is a rock phenomenon located in Varna Province, Bulgaria, on the road between Varna and Sofia around several villages just west of Varna. It consists of several groups of natural rock formations on a total area of 7 km². The formations are mainly stone columns between 5 and 7 metres high and from 0.3 to 3 metres thick. The columns do not have solid foundations, but are instead hollow and filled with sand, and look like they are stuck into the surrounding sands, which gives the phenomenon its name.
In order to be preserved, Pobiti Kamani was designated a natural landmark in 1937.
There are a number of theories regarding the phenomenon's origin, divided roughly into two groups — supporting an organic or a mineral origin. According to the former, the formations are the result of coral activity, while the latter explain the phenomenon with the prismatic weathering of the rocks, the formation of sand and limestone concretions, or lower Eocene bubbling reefs.
