Castellana Caves, Show cave in Castellana Grotte, Italy.
Castellana Caves are a cave system in the Apulian municipality of Castellana Grotte that extends over several kilometers through limestone and reaches about 120 meters (roughly 400 feet) below the surface. The interior temperature remains constant year-round at about 16 degrees Celsius.
The speleologist Franco Anelli first entered the system in January 1938, discovering the deep shaft known as La Grave and further chambers. His work led to systematic exploration and the later opening of the caves to visitors in the following years.
The system takes its name from the nearby town of Castellana, while the grottos have served as a popular destination in Apulia since opening to visitors. Inside, halls such as the White Cave and the Cavern of Monuments carry Italian names referring to their appearance and discovery.
Visitors can choose between two guided routes: a shorter walk of about one kilometer or a longer path extending around three kilometers. Sturdy footwear is recommended, as the paths pass through natural formations and can be uneven in places.
In the so-called White Cave, bright alabaster and calcite crystals reflect light, creating soft shading on the walls. This section is considered one of the brightest natural spaces in the entire system.
