Giant Cave, Trieste

The ‘Giant Cave’ is located on the Italian side of the Karst region, close to the village of Borgo Grotta Gigante. Its central cavern is 107 m (351 ft) high, 65 m (213 ft) wide and 130 m (430 ft) long; for this reason it was recorded in the 1995 Guinness Book of Records as the world's largest cave (even if this record was broken in 2010).

The Giant cave, whose origin dates back to 10 million years ago, is made up of mainly limestone rocks and dolomites ones, formed between 100 and 30 million years ago.
It can be visited all year round as it’s constantly theatre of many different activities: from scientific research to educational and tourist projects.
The Giant Cave has three natural entrances, two of which constitute the entrance and exit of the tourist route respectively.
The path equipped for tourist visits is 850 meters long and allows you to reach the depth of 101 meters below the surface; the guided tours last about an hour.
