Overview
The megalithic sanctuary of Ġgantija stands on the edge of the Xagħra plateau on the island of Gozo in Malta. Constructed during the Neolithic Ġgantija phase (c. 3600–3200 BCE) and utilized continuously through the Tarxien phase until approximately 2500 BCE, the complex consists of two adjacent multi-apsed temples enclosed within a single continuous D-shaped boundary wall. Some of the outer coralline limestone megaliths measure over 5 meters in length and weigh upwards of 50 tonnes, leading later folklore to attribute their construction to a mythical giantess, Sunsuna.
The South Temple is the older, grander structure (c. 3600 BCE), laid out along a five-apse trefoil plan with an elevated central corridor leading through monumental megalithic trilithon gateways. The North Temple, erected alongside it around 3200 BCE, features an intimate four-apse arrangement. Both monuments demonstrate advanced stereotomic planning: dual layers of masonry combine hard, weather-resistant Coralline limestone for the external load-bearing facades with softer, fine-grained Globigerina limestone for interior altars, decorative doorframes, libation basins, and decorative pitted screens.
"A giantess named Sansuna ate nothing but broad beans and honey; bearing a child upon her shoulders, she built these towers of enormous stones in a single night."

The site was first cleared of debris in 1827 under the direction of John Otto Bayer, the British Lieutenant-Governor of Gozo, and was drawn in detail by artist Charles de Brochtorff before modern weathering accelerated. Scientific excavations were undertaken in the 1930s by Luigi Ugolini and in the 1950s by John Davies Evans and David H. Trump (1954–1955). Between 1987 and 1994, the landmark Cambridge Gozo Project directed by Caroline Malone, Anthony Bonanno, and Colin Renfrew excavated the nearby Xagħra Stone Circle (Brochtorff Circle), discovering a subterranean hypogeum with collective burials, stone statuettes, and mortuary offerings that conclusively linked the temple rituals to an island-wide religious community.
Ġgantija was inscribed as a UNESCO World Heritage Site in 1980 (ref. 132), establishing the listing that was later expanded in 1992 to include the five other prehistoric Maltese temples. Placed in dialogue with Ħaġar Qim and the subterranean Ħal Saflieni Hypogeum on Malta, as well as the earlier hunter-gatherer enclosures at Göbekli Tepe and Britain’s later Stonehenge, Ġgantija documents the earliest phase of monumental stone architecture in the Mediterranean.
