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). Nowadays, the sites are managed by Heritage Malta, while ownership of the surrounding lands varies from site to site. Apart from these, there are other megalithic temples in Malta which are not included in the UNESCO World Heritage list.
