2/ Kunětická hora Hill – former quarry

Altitude: 235–307 m above sea level
Area of the natural monument: 27.3 ha
Material: Tertiary volcanic rock tephriphonolite, in places porcellanite (metamorphosed siltstone)


Stone was mined at the southern foot of Kunětická hora hill – in the 15th century the stone was used to build a castle on the top of the mountain and more intensive mining took place in the 19th century in connection with the construction of the Prague - Olomouc railway and the surrounding roads. Mining destroyed the most valuable steppe habitats. However, quarry walls became a partial replacement for the destroyed xerophytic habitats. Nowadays, the former quarry is overgrown with trees.
