Grotta Gigante

The exceptionally large size of the main underground chamber of the Grotta Gigante, situated near Borgo Grotta Gigante, in the municipality of Sgonico (Trieste), enabled it to enter the Guinness Book of Records as the world's largest show cave in 1995. The cave can be accessed by a downhill tunnel; the flights of steps lead down to the main chamber, which is 98,50 metres high,  76,30  metres wide and 167,60 metres long (total volume 365.000 m3): the cave is crossed by a geodetic pendulum for the study of earth tides.
