An erratic boulder with a circumference of 13 meters. In pagan times it served as a sacrificial table. Later, the knight and robber Maćko Borko from Strzmiel took a liking to him. He lived in the years 1360-1426. He became famous for several daring robberies and kidnappings. He also sent an envoy to King Eric of Pomerania, who sought an agreement with Jagiełło against the Teutonic Knights. Apparently, Maciko loved lying on this boulder, which is where its name comes from.
