2 Euros Mnajdra Temples

Malta's 2018 commemorative issue marks the Mnajdra temple complex, a Neolithic site on the southern coast of Malta dated to roughly 3600–2500 BC — making it among the oldest freestanding stone structures on earth, predating Stonehenge and the Egyptian pyramids. Mnajdra was designated a UNESCO World Heritage Site in 1980 alongside the nearby Ġgantija and Ħaġar Qim temples.

The site suffered deliberate vandalism in April 2001, when attackers toppled and shattered over 60 megaliths. Restoration took months and prompted the Maltese government to erect protective tent structures over the complex.
