The sandstone bust of the Russian Tsar created by Prague sculptor Tomáš Seidan in 1877 is installed on a rock below the lookout on so-called “Peter's Height”.
It commemorates an event when on 11 November 1712, Peter made a bet and rode up to the lookout on a horse without a saddle. Since no path or road led to the top of the hill back then, the tsar showed tremendous riding skills as he rode up through the steep rocky terrain. In 1909, the original weathered bust was replaced by an identical copy.
Memorial plaques with odes celebrating Peter the Great were installed on the rock in the 19th century.
