One of the gems of Papuk―a unique kind of rock that was formed 85 million years ago in the Late Cretaceous, due to volcanic activities. When this lava cooled near the surface it crafted 'albite rhyolite'; a rare acidic rock that split into four- and five-sided columns. Some tiny crystals of 'zircon' and 'apatite' are locked in the rock and reveal its age, and link it to historical tectonic movements. Unlike typical basalt columns, rhyolite makes it a global rarity, and thus earning protection as Croatia's first geological monument in 1948. Today, it is the most iconic site in the Geo-/Nature Park.
