Kuncler quarry is located on the edge of the Ljubljana
Marshes, between Brezovica and Vrhnika, in a village called Lesno Brdo. It is
named after a former owner and was declared a natural geological monument in 1991. In the past centuries they
excavated black and gray limestone from its ground. The limestone in the quarry
is from the Triassic period (about 225
million years old) and is appreciated as an architectural stone, because of its beautiful black and white
contrast (result of calcite veins in limestone). The material from this quarry
was used for several well-known pieces:
‘’Black King’’ in St. James's Parish Church (St. Jacob’s) and two stone Herculeses on the portal of Seminary in
Ljubljana.
Today Kucler quarry is known as a fossil shell site and for its wonderful case of tectonic fold. At the quarry you can also find a Geological key showing the major rock types of the
region and a display of sculptures from different Stonemason workshops
that took place in this very same quarry.
