Napoleonas stone is a man-made boulder, triangular pyramid cut at the top shape, approximately 1.25x1.2x0.9 m in size and up to 0.5 m in height. In 1925 the story of the local historian Jurgis Elisonas was written that a plate, a spoon and a fork were carved on the stone, with which Napoleon ate while traveling in 1812 to Moscow. Other researchers are reluctant to agree with folklore, and therefore believe that the Salakas stone should be associated with 1554, when the delimitation of land holdings between the Vilnius diocese and Salakas-Luodžiai landowners Petkevičius. Petras Tarasenka tried to prove that the symbols of the sun cult are carved in the Salakas stone. Subsequent researchers agreed and stated that the stone is not only an altar of the cult of the sun, but also an object that testifies to the arrival of Christianity in north - eastern Lithuania. In 1970 during archeological excavations near the stone, individual archeological finds were discovered in the cultural layer - shards of pots.
