Excavations in the relatively small quarry began around 1950, primarily to fulfill the needs of local construction and restoration work.
Travertine is a biochemical sedimentary rock. If you look closely, you will see impressions of mosses, twigs, seeds, cones, leaves, grasses and even snail shells and tree trunks. It can be brownish-yellow, greyish or reddish in colour. The red colour comes from iron oxides. The rock darkens over time due to oxidation. In the central part of the quarry, you can see that water containing suspended clay particles from shale occasionally flows over the black shaley claystones and the travertine, staining the top layer black. The trail will lead you to a tufa-forming spring, where the rock is still formed today.
