The grotto was discovered by Anthony Xerri while he was drilling for a well to provide water for his family home.
The cave remained hidden from the public until the family realized the significance of the geological formations during the digging process.
The temperature inside the grotto remains consistently cool throughout the year compared to the exterior Maltese climate.
Many of the stalactite and stalagmite formations have developed distinct shapes that local guides often point out during tours.
The cave is situated in an area of Gozo known for significant prehistoric archaeological activity, including the nearby Ġgantija temples.
Xerri's Grotto is an underground limestone cave system discovered in 1923 during the excavation of a residential water well. The grotto is located directly beneath a private family home in the town of Xagħra on the island of Gozo. It features an array of stalactites and stalagmites formed by centuries of groundwater seepage. Visitors enter the grotto by descending a spiral staircase that leads approximately 10 meters below ground level. The cave is relatively small and can be viewed in its entirety within a short visit. The site remains under the stewardship of the Xerri family, whose ancestors originally uncovered the cavern. The formations include diverse shapes, some of which are illuminated to highlight their crystalline structures. The cave remains a preserved example of subterranean geological activity within a typical Maltese residential area.

Wear sensible, non-slip footwear as the ground inside the cave can be damp or uneven.
The cave is located inside a private house, so be prepared to knock or alert the hosts of your arrival.
Consider visiting in combination with the nearby Ninu's Grotto, which was also discovered under a private home in Xagħra.
Do not expect a large-scale commercial cavern experience; this is a small, intimate site accessed through a private residence.
Do not touch the stalactites or stalagmites, as natural oils from skin can damage the growth process.
