Some of the megaliths of the Ġgantija Temples exceed five metres in length and weigh over fifty tons. Giants were believed to have constructed these prehistoric temples and that is from where their name originates. Certainly, these ancient structures represent a phenomenal cultural, artistic and technological development in a very early period in human life.
Consisting of two temples which date back to between 3600 and 3200 BC, the Ġgantija Temples are included in the UNESCO World Heritage List. The site is considered as one of the oldest free standing monuments in the world, preceding Stonehenge and the Egyptian pyramids.
Notwithstanding their age, the temples survive in a considerably good state of preservation. This is noticeable in the boundary wall that encloses the two temples, and which is built in rough Coralline Limestone blocks. The hard-wearing Coralline Limestone is used extensively at Ġgantija, and is one of the reasons behind the preservation of the monument. The softer Globigerina Limestone was reserved for inner furnishings, such as doorways, altars and decorative slabs.
