The Tarxien phase marks the peak of the temple civilisation. This phase is named after the temple-complex at Tarxien, a couple of kilometres inland from the Grand Harbour. To it belong the last two stages in the development of the temple plan. The western temple at Ġgantija represents, along with other units in Tarxien, Ħaġar Qim and L-Imnajdra, the penultimate stage in development, that is, the introduction of a shallow niche instead of an apse at the far end of the temple. The final stage is testified in only one temple, the central unit at Tarxien, with its three symmetrical pairs of apses. The Temple culture reached its climax in this period, both in terms of the craftsmanship of pottery, as well as in sculptural decoration, both free-standing and in relief.
