It is a large stone – an ancient Latgalian cult stone. Its length is 5.3 m, width – 3.5 m, height – 1.8 m. It is assumed that the stone was used as a border stone. There are two carved crosses and a sign resembling a horseshoe, looking like a deer or bullhead. Due to this, the boulder received its name. On a side of the stone, there is one more carved diamond-shaped sign. Old people say that if you touch the stone it can take all your diseases and will give you power and energy.
