Wietrznia Reserve in Kielce, Nature reserve in southeastern Kielce, Poland.
The Wietrznia Reserve is a nature reserve near Kielce where three excavation sites expose ancient rock formations from over 360 million years ago. These areas reveal layers of limestone and dolomite that tell the geological story of the region.
The site operated as a limestone quarry from 1893 until 1974, supplying materials for building and industry across the region. When mining stopped, the area was protected as a nature reserve to preserve its geological formations.
The education center here teaches visitors how people have worked with limestone and shaped the landscape around them. This work connects the reserve to the broader story of the Świętokrzyski Geopark and its role in the region.
The reserve has two parking areas and an educational trail with information boards at key points. Allow about three hours to walk the path and see all the exposed geological formations.
Five caves lie within the reserve, with one extending over 60 meters and containing minerals like calcite, quartz, and pyrite. These underground spaces formed naturally through water erosion in the limestone and display rare mineral formations.
