Jabloňka, Nature monument in Libeň, Prague, Czech Republic

Jabloňka is a 1.25-hectare natural monument on the right bank of the Vltava in Libeň, on a steep slope between Pelc-Tyrolka and the mouth of Trojská street. Its old quarry exposes Skalecké quartzite beds dipping 60–70 degrees southeast, with younger dark shales on the south side and older quartzites on the north. A small chateau, zámeček Jabloňka, stands within the protected area.

The site functioned as a quarry until the late 1800s, where stone was extracted for construction purposes. This industrial past ended when the area transitioned to protected status.

The name Jabloňka refers to an apple tree, recalling the orchards and gardens that covered the slope until the end of the 19th century. A small chateau of the same name stands within the 1.25-hectare protected area, which lies on the right bank of the Vltava between Pelc-Tyrolka and the mouth of Trojská street.

The site is located in an urban area and relatively accessible. Wear sturdy footwear as the terrain is steep and rocky in places.

The old quarry face exposes Skalecké quartzite beds tilted 60–70 degrees southeast, with younger dark shales on the south side and older quartzites on the north, a result of Variscan uplift. The 1.25-hectare site also holds the Jabloňka chateau within its boundary.
