Xerri's Grotto is a cave in Xagħra, Gozo, Malta. It was discovered by local resident Anthony Xerri in 1923[1] or 1924[2] while digging a well under a private house. Xerri's Grotto is not far from another underground feature, Ninu's Cave, which was discovered in 1888 in a similar fashion, when a well was being dug under a private house.
The grotto is larger than Ninu's Cave. It contains various calcified formations, including stalactites and stalagmites, some of which resemble a tortoise, a vulture, giraffes or elephant's ears. Some other formations which developed as a result of the calcification of tree roots can also be seen.[3]
The entrance to the cave is down a 10m spiral staircase, built into the original well shaft. The cave was extended during World War II when the family used it as an air raid shelter.[2]
Today, the cave is illuminated by electric lights, and is open to the public with tours being given by the owners of the house.
