The most famous of them are the Devil’s Heads (Čertovy hlavy), two gigantic rock reliefs carved into sandstone cliffs rising above a pine forest. Standing approximately nine metres tall, they are among the largest rock sculptures of their kind in the country. Levý created the impressive work between 1841 and 1846, long before becoming one of the most celebrated Czech sculptors of the 19th century. His later works can be found in Prague’s Church of St. Charles Borromeo and St. Vitus Cathedral.
The sculptures are freely accessible via the blue hiking trail starting in Želízy. Along the route, visitors can also explore Klácelka Cave and the nearby area known as Blaník, featuring reliefs of Jan Žižka, Prokop the Great, and legendary dwarves forging weapons for the Knights of Blaník.

Additional highlights include the Snake, carved into a rock and split by an axe, and the Harpist, a striking depiction of a woman playing a harp.
