Grotta Regina del Carso: The Jewel of the Gorizia Karst
Hidden within the rugged landscapes of the Gorizia Karst lies one of the region's most stunning subterranean wonders. Known as Grotta Regina del Carso (or Jama Kraljica Krasa in Slovene), this cave stands as a testament to the beauty and complexity of karst topography—a landscape formed from the dissolution of soluble rocks such as limestone.
The Discovery and Early Exploration
The cave was first brought to light on January 2, 1972, by Dominik Grillo. The initial phase of exploration was not without its challenges; cavers had to work diligently to unblock the entrance before they could venture inside. Once access was secured, they discovered what would become the most extensive and aesthetically impressive cave in the Gorizia Karst area.
By the end of 1972, a formal survey of the cavity was completed. This discovery sparked a passion for speleology—the scientific study of caves—leading to the formation of a dedicated organization the following year: the Gruppo Speleologico Talpe del Carso (the "Karst Moles speleological group," or Jamarski Klub Kraški Krti in Slovene). To support their ongoing work, the group established a headquarters, known as a baita (lodge), located just a few meters from the cave's entrance.

Over the subsequent years, exploration continued as cavers widened the cave's passages and uncovered new branches. These efforts expanded the known total length of the cave to 320 meters (1,050 ft).
Beyond mere exploration, the cave became a site for structural testing. In 1973, glass slabs were strategically placed in specific areas of the cave to monitor the solidity of the subterranean space. These slabs served as a critical indicator during the 1976 Friuli earthquake; because the glass remained intact, it proved that the Karst region had been spared from the most destructive forces of the quake.
Following these events, the cave attracted the attention of the scientific community. Geologists and biologists conducted extensive research on the cave's geomorphology (the study of physical features of the surface of an area) and the unique animal species that inhabit the dark, sheltered environment of the cavity.

Frequently Asked Questions
Who discovered Grotta Regina del Carso?
The cave was discovered by Dominik Grillo on January 2, 1972.
What is the total length of the cave?
Through the discovery of new branches and widening of the cave, the total extension reached 320 meters (1,050 ft).
What is the Gruppo Speleologico Talpe del Carso?
It is a speleological group (known in Slovene as Jamarski Klub Kraški Krti) founded in 1973 following the discovery of the cave. They maintain a lodge (baita) near the cave entrance.
How did the cave provide information about the 1976 Friuli earthquake?
Glass slabs installed in 1973 to test subterranean solidity remained intact during the 1976 earthquake, indicating that the Karst region avoided the quake's impact.
What scientific studies have been conducted in the cave?
Geologists and biologists have performed research focusing on the cave's geomorphology and the various animal species living within the cavity.
