This year, the Aggtelek National Park celebrates a remarkable convergence of anniversaries: the Gömör–Torna Karst has been part of the World Heritage for 30 years, the National Park itself turns 40, and it was 200 years ago that Imre Vass passed what was then considered the most promising endpoint of the Baradla Cave – the so-called “Vaskapu” (Iron Gate).
Imre Vass, the “certified surveyor of Gömör County” in the 19th century, was a curious, perhaps somewhat restless man. He often visited the cave opening beneath Baradla Hill, near the village of Aggtelek. His explorations reached the section known as Vaskapu in 1821, where the limitations of contemporary techniques brought him to a halt. “Thus far and no further,” he declared, and left his signature on the spot: “Vass Imre 1821.” This inscription remains visible today, and experienced tour guides can point it out on cave tours.
