The Grotta Gigante di Sgonico, in the heart of the Triestine Karst, is a fantastic place that is almost ten million years old, two hundred and eighty meters long, sixty-five wide and one hundred and seven in height for a total volume of 600 thousand cubic meters.
The Giant Cave (in Slovenian Briška jama), in fact, is really a cavity from the "Guinness Book of Records". One would say "something unique in the world". So big that it can even host St. Peter's Basilica inside.
The Grotta Gigante is truly special. It is the only one of this size that can be visited without the need to use specific equipment and without speleological training.

His own story
Its formation probably originated from the flow of two overlapping watercourses, whose diaphragm that divided them, at a certain point, collapsed giving life to this impressive karst cave.
Officially, the cave was discovered in 1890. In fact, it was known well before. In fact, in 1840 it was partially explored by Federico Lindner. Complete exploration by the "Trieste Tourist Club" followed in 1890.
Subsequently, work began on the construction of the stairs that led from the entrance to the base of the cave. They lasted three years, culminating in a historic inauguration.
It was July 15, 1908, and the Grotta Gigante was opened to Trieste, illuminated by thousands of candles, lanterns and torches. A spectacular 100-flame chandelier was brought down from the vault, while the music of the local band resounded inside, while intoning "Siegfried".
We "go down" to the cave
More than a hundred years have passed since then. The cave has gradually changed and improved to facilitate visits. In fact, it benefits from a modern electrical system that does not in any way detract from the charm of its magical atmosphere and those very "lunar" environments that characterize it.
Almost certainly, the Grotta Gigante is one of the most important in Italy. Each year, more than 90,000 visitors experience a unique experience in this cave capable of giving indelible memories.
The visit to its interior lasts about an hour and takes place with the accompaniment of a specialized guide, taking place along a path of eight hundred and fifty meters that goes down to a depth of one hundred meters at a constant temperature of 11 degrees.

Its entrance consists of a natural opening that was already used as an access for tourists in 1908. From here a series of steps, 500 to be exact, lead to the "Great Cavern", a room of extraordinary dimensions that opens to a depth of eighty meters.
Already from the Grand Staircase you realize that this cave is truly unique in terms of beauty. Seeing it from above is exciting. It seems to see, at night, a distant valley, with lighthouses that illuminate a beautiful arch from which large stalactites descend.
Especially at the base of the cave, the cave impresses with its beauty and the colorful colors (yellow, pink and red) skilfully brought up by the lighting system.
But even in the rest of the cave, the sight continues to be incredibly beautiful. Among the largest and therefore beautiful concretions: the Pulpit or La Palma. But also the Palazzo delle Ninfe or the Belvedere with a myriad of hanging stalactites and stalagmites.
Towards the end of the descent you will find Ruggero's column: the largest stalagmite in the cave (12 meters high and 4 meters wide). Just looking at it excites you.
The adjacent room also houses the geophysical research station which has sophisticated instruments for studying the movement of the earth's crust.
The deepest point that can be reached by tourists is located one hundred and one meters from the entrance, between paths formed with limestone formations, columns, stalactites and stalagmites. Reaching a depth of two hundred and fifty-two meters, however, you arrive at the "Altar Room" from where you can observe the "Secret Grotto".
Here too there are stalactites and a small calcite basin filled with water, from which several secondary galleries branch off.
To return to the surface, follow the "Carlo Finocchiaro" path, a panoramic staircase from which you can enjoy a spectacular view of the entire cavity. From here you continue through a tunnel dug into the rock, which leads to the Belvedere, a ninety-five meter high terrace overlooking the "Great Cavern".
Near the exit, however, it is also possible to admire the skeleton of a Cave Bear, a specimen that disappeared at the end of the last Ice Age.

The Reception Center
The Grotta Gigante Visitor Center has a multimedia room to allow people with disabilities to explore, thanks to a precise laser scanner survey carried out by the National Institute of Oceanography and Experimental Geophysics.
The educational center and the scientific speleological museum, on the other hand, are two equally interesting neighboring realities that further enrich the visit to Borgo Grotta Gigante. It is particularly suitable for those who wish to deepen the scientific, speleological and archaeological / geological aspects of the cave, studies relating to the terrestrial tides, as well as studies on the karst territory that surrounds it.
Shows in the "Grotto"
Over the years, numerous shows and very special events have been organized inside the cave.
What was it about? Everything and more'. From theatrical performances to extreme sports, passing through tastings of typical products (wine, salami, oil, craft beer) of the Karst or themed shows organized for both adults and children.
Inside, of course, there was no lack of very particular "descents". Click to see that of the Befana. Or authentic "light and sound" shows. Click to watch "Paracosm dj set by Mazare".
