Ggantija is the earliest of the four major temple complexes on Malta, and probably dates to sometime around the middle of the fourth millennium. One source (Bonanno 1997) gives 3600 - 3300 BC, although other dates may be found in various reference books.
In the plan of Ggantija, the basic trefoil (three-lobed) shape was modified by the addition of pairs of side apses. The complex consists of two temples, one having five apses and the other having four apses plus an end niche. The whole is enclosed by an outer wall. The temple axes are oriented to the southeast.
