Dívčí hrady and Parus major
Great tit singing on the hill of Dívčí hrady, new year evening. In the notch of the road there is an exposed profile with Dvorecko-Prokop limestones with rich trilobite, brachiopod, cephalopod and other fauna. In the notch of the railway, a vein of mines protrudes in the overgrown outcrop and breaks through the upper positions of the Dvůr Králové-Prokopské limestones. It is the only accessible minet outcrop breaking through the Devonian sequence in the Barrandien, important evidence of the Variscan age of mines in and around Prague.
