MALTA

This cover from Malta depict a single stamp issued in 2009, celebrating the Megalithic Temples of Malta. The Megalithic Temples of Malta are several prehistoric temples, some of which are UNESCO World Heritage Sites, built during three distinct periods approximately between 3600 BC and 2500 BC on the island country of Malta. Archaeologists believe that these megalithic complexes are the result of local innovations in a process of cultural evolution. This led to the building of several temples of the Ġgantija phase (3600–3000 BC), culminating in the large Tarxien temple complex, which remained in use until 2500 BC. After this date, the temple-building culture disappeared. The Ġgantija temples were listed as a UNESCO World Heritage Site in 1980. In 1992, the UNESCO Committee further extended the existing listing to include five other megalithic temple sites. These are Ħaġar Qim (in Qrendi), Mnajdra (in Qrendi), Ta' Ħaġrat Temples (in Mġarr), Skorba Temples (in Żebbiegħ) and Tarxien Temples (in Tarxien).[
