Lysa Hora, Nature reserve and historic fortress site in Holosiiv district, Kyiv, Ukraine

Lysa Hora is a wooded hill in the Holosiiv district of Kyiv, Ukraine, near the point where the Dnipro and Lybid rivers meet. The top remains free of dense vegetation and offers open views, while the slopes are covered with trees and trails.

The Russian army built a fortress on the hilltop in 1872, which later served as an execution site for political prisoners between 1906 and 1917. After the fall of the Russian Empire, the structure lost its military function and gradually decayed.

The name Lysa Hora, "bald mountain", comes from a belief that the hilltop was scorched by lightning striking places where unclean spirits gathered, leaving a bald patch. Today the hill draws neopagans, Tolkienists and youth subcultures who meet on its slopes.

The hill lies in the Holosiiv district between Saperna Slobidka and Bahrynova Hora, reached by Lysogirska and Beskydska streets; the Lysa Hora regional landscape park, created in 1994, covers 137.1 hectares. The Lysogirsky fort is managed by the Kyiv Fortress museum, and the wooded slopes are cut by the Northern and Southern Lysogirsky ravines. The highest point, where the rampart meets the moat, stands at 169.2 m.

The hill's highest point, where the defensive rampart meets the ditch, stands at 169.2 m above sea level, 77 m above the Dnipro. Archaeologists found Trypillia culture material on the northeastern cape, redeposited when the fort was built. The fort's brick-lined tunnels, up to 40 m long, still show their gate hinges.
