Blue Stone (Russia)

Blue Stone, or Blue Rock (Russian: Синь-камень) is a type of pagan sacred stones, widespread in Russia in areas historically inhabited by both Eastern Slavic (Russian), and Volga Finnic tribes (Merya, Muroma[1]).

If used as a personal name, Sin-Kamen (Blue Rock) usually refers to the most famous sacred stone of this kind, located on a shore of Lake Pleshcheyevo near Pereslavl-Zalesskiy.

[3] Sin-Kamen' is a grey boulder of coarse-grained quartz-biotite schist that used to be venerated by the Meryans and the pagan Slavs on the shore of Lake Pleshcheyevo not far from the early medieval town of Kleshchin.

A century ago, the stone used to be as tall as a man but it has steadily sunk into the ground ever since.

Although it is widely believed that the stone was overthrown from a pagan sanctuary on top of Bald Hill at the bidding of Tsar Basil IV, early descriptions locate it in the vicinity of the Pereslavl Monastery of Sts.
