A hidden chamber, buried for over three centuries beneath Halych Castle in western Ukraine, has finally been accessed by archaeologists. The room, concealed under 150 cubic metres of soil and debris, was sealed after a cannon bombardment during the Turkish-Polish War in 1676 caused a wall collapse.
The chamber was uncovered after years of meticulous manual excavation to preserve its archaeological integrity.
In 2023, a ventilation shaft hinted at the chamber’s existence. Since then, experts painstakingly cleared the site without heavy machinery. Vladimir Oleynik of the Ancient Galich National Reserve stated the collapse likely occurred during the 1676 attack, which destroyed parts of the castle’s defenses.
Mystery of the Chamber’s Purpose
Initial findings suggest the room served as a casemate—a vault for storing weapons or valuables during conflicts. However, a small gap in one wall points to a potential tunnel network, sparking intrigue. Local legends speak of underground passages, including a tale of a maiden escaping with her lover via tunnels, aided by a bribed guard.
Could this gap lead to a legendary tunnel system? Researchers are investigating.
Castle’s Rich History
Halych Castle, originally a 12th-century wooden fort, was rebuilt in stone in the 14th century. Perched on a rocky outcrop overlooking the Dniester River, it underwent redesigns in the 17th century before falling into ruin.
The castle’s strategic location made it a key defensive site for centuries.
Ongoing Exploration
While public access remains restricted, archaeologists aim to uncover more about the chamber’s secrets. The site adds to Ukraine’s historical tapestry, which includes a 2018 discovery of 4,500-year-old bones adorned with tar markings—a ritual unlike any seen in Europe.
As excavations continue, researchers hope to reveal connections between the chamber, potential tunnels, and the castle’s storied past.
