Pražský zlom

Pražský zlom is a geological fault in Hloubětín where layers of quartz rocks and bluestone are exposed at the surface. The fracture cuts through the ground at a northeast angle, creating a visible scar where two sections of Earth's crust have shifted apart.

This fault formed during the Ordovician and Silurian periods, when tectonic movements fractured the Earth's crust hundreds of millions of years ago. The displacement created by these ancient forces shaped the geological structure of the Prague region.

The geological site serves as an educational resource for scientists and students studying rock formations and tectonic processes in Central Europe.

The site is small and easy to reach on foot once you know its location. Since it is a protected natural area, visiting during daylight hours is recommended and sturdy footwear is helpful when exploring the exposed rocks.

Workers discovered this fault unexpectedly while building tunnels beneath Vítkov hill in the early 2000s, which helped geologists understand the structure better. The finding revealed that this ancient fracture extends deep underground across the city.
