The megalithic temple complex on Gozo in Malta is Ġgantija, part of the UNESCO-listed Megalithic Temples of Malta.
Located near Xaghra, Ġgantija consists of two Neolithic temples built from enormous limestone blocks. The name means “place of giants,” reflecting the local belief that only giants could have moved such stones. Archaeological evidence places the temples roughly between 3600 and 2500 BCE, making them older than the Egyptian pyramids.
Ġgantija was not listed as an isolated World Heritage property forever. UNESCO first inscribed the temples in 1980, then expanded the listing in 1992 to include other prehistoric temple sites across Malta and Gozo. Tarxien, Mnajdra, and Ħaġar Qim are also part of that wider UNESCO property, but they are separate temple complexes. The answer is therefore the specific site named in the question, not the broader group.
