Magnetovec – Skalní hřib, Nature reserve south of Velké Březno, Czech Republic

Magnetovec – Skalní hřib is a protected rock formation in the České středohoří region. The structure consists of two distinct volcanic layers shaped by erosion into a mushroom form, with a wider cap balanced on a narrower pedestal.

The site received official nature reserve status in 1992, establishing formal protection for this geological formation. This designation ensured long-term conservation of the rock structure within the region.

The mushroom shape comes from two basanite lava flows: the lower, more porous layer weathered into a thin stem, while the upper plug of harder rock forms the cap. The Czech name Skalní hřib means "rock mushroom".

The rock mushroom stands on the south slope of the 520 m Magnetovec hill, between Velichov and Byňov, on the right bank of the Homolský potok valley. A green-marked trail from Velké Březno connects to a circular route set up in 2002 that passes the monument. The protected area covers 6.3 hectares.

The 8-metre-high mushroom stands on the southern slope of the 520 m Magnetovec hill near Velké Březno, above the Homolský potok valley. It was declared a protected natural monument on 27 April 1992, covering 6.3 hectares.
