The Tarxien Megalithic Temples are to be protected from any further atmospheric deterioration following the approval by the MEPA Board of an overlying protective, lightweight structure at this World Heritage site.

The protective structure, which has a total footprint measuring approximately 2700m², is to have an undulating design with a translucent glass fibre membrane supported by a lightweight triangulated metal structure. This intervention which is reversible, will shelter and protect the vulnerable structures of this site from direct rainfall, solar radiation and ground humidity. This temple site is renowned for the rich and intricate stonework, which includes depictions of domestic animals carved in relief, altars, and screens decorated with spiral designs and other patterns.

These temples which were discovered in 1914, consist of four separate, but attached, temple structures. Many of the decorated slabs discovered on site were relocated indoors for protection at the Museum of Archaeology in Valletta.
