Friar & Nun Rocks

Friar & Nun Rocks are two cliff formations made of volcanic dacite tuff that rise distinctly above the ground near Sirok in Heves County. The rocks have developed a columnar structure through natural weathering and erosion over time.

These formations emerged during the Miocene period, roughly 17 million years ago, when powerful volcanic activity shaped the Carpathian region. The geological processes that created them continue to influence how the landscape looks today around Sirok.

The rocks are named after local stories about a friar and a nun, reflecting how people in the area connect them to spiritual figures. This naming shows how the landscape becomes tied to the everyday conversation and memory of the community.

You can reach the rocks through marked hiking trails that start from Sirok village and wind through the Bükk mountain landscape. Visit during warmer months when the paths are easiest to walk and the weather is most stable.

The columnar structure of these rocks developed through a rare combination of volcanic cooling and erosion that aligned them into parallel standing columns. This pattern is uncommon in the area and makes them a distinctive geological example of how natural forces shape the landscape.
