Zwercheck, Mountain summit in Bohemian Forest, Czech Republic.

Zwercheck is a mountain summit located on the border between Germany and the Czech Republic, rising to approximately 1,334 meters in elevation. The peak stands within a forested region that forms the defining landscape feature of this area.

The mountain has carried two names throughout history, reflecting its position between German and Czech territories: Zwercheck in German-speaking regions and Svaroh in Czech lands. This dual naming reveals the long history of the border that has divided these regions.

The German name Zwercheck and the Czech name Svaroh both refer to this 1,334-metre border summit. A wooden lookout tower stood below the peak in the 1870s, according to an 1878 guidebook, offering a view of Černé jezero. The Juránkova chata mountain hut, built in 1932 at the saddle toward Jezerní hora, burned down shortly before the Second World War.

Only two official marked trails reach the summit: one from Oberhaiderberg near Lohberg, the other from the Scheibensattel on the Brennes road between Lohberg and Bayerisch Eisenstein. A route along the state border is rarely walked by locals; a wild path follows the border northwest to the Osser in about three hours.

A wooden lookout tower stood below the summit in the 19th century, according to an 1878 guidebook, offering a view of Černé jezero (Black Lake). The Juránkova chata mountain hut, designed by architect Václav Neckář with 50 beds, was built in the saddle toward Jezerní hora in 1932 and burned down shortly before World War II.
