Strázsa-hegy Cave, Natural cave in Esztergom, Hungary.
Strázsa-hegy Cave is a limestone cavern carved into Strázsa Hill with multiple chambers and passages that wind through different levels. The cave features natural water channels and rock formations created over thousands of years by water movement and mineral deposits.
The cave was discovered in 1946 by brothers Károly and Rezső Várhidi following an initial crack noticed by quarry workers in 1944. Scientific studies have since documented its geological features and importance to the region's karst landscape.
Local caving clubs maintain the cave's preservation while conducting research and educational programs about its geological importance for visitors.
The cave maintains cool temperatures and high humidity throughout the year, so warm and moisture-resistant clothing is essential. Visits typically require advance booking and sturdy footwear suitable for uneven ground.
The cave contains rare minerals including aragonite, gypsum crystals, and goethite that show evidence of hydrothermal activity. These minerals are unusual for the region and make the cave scientifically significant.
