The Ggantija Temples are a group of megalithic structures located on the island of Gozo, part of the Malta archipelago. Dating back to around 3600-3200 BC, they are among the oldest free-standing stone structures in the world. The temples are built from large limestone blocks and are characterized by their impressive architecture, including curved walls and intricate stone carvings. These ancient temples are part of the Maltese prehistoric sites and were designated a UNESCO World Heritage Site in 1980. The Ggantija Temples are believed to have been used for religious rituals, possibly related to fertility, and provide valuable insights into the lives of the prehistoric inhabitants of Malta.
