Mnajdra Qrendi is a complex of prehistoric megalithic temples opposite the Islet of Filfla, located just 300 m from the archaeological site of ġaġar Qim. Rocks, including coral limestone, were used to erect buildings. The time of creation of monumental places of worship is estimated for the period from the third to the middle of the second millennium BC. Mnajdra Qrendi has been on the UNESCO World Heritage List since 1992.
Mnajdra Qrendi is one of many discovered megalithic objects on the islands of Malta and Gozo. Buildings erected from huge stone blocks without the use of mortar required advanced engineering technique. It was not possible to determine how former builders coped with mehirs of several dozen tons.
In addition to Mnajdra and Ħaġar Qim, four other Maltese megalithic structures have been added to the UNESCO World Heritage List: Ta 'Ħaġrat, Skorba, Tarxien and Ġgantija. Apart from the list were smaller, less well-preserved objects, such as the Kordin Temples and the Tas-Silġ archaeological site.
