These are the oldest and the most impressive of the megalithic temples in the Maltese islands. Built during the Neolithic period, the ruins are more than 5,500 years old, predating Stonehenge and even the pyramids of Egypt. It is the coralline limestone used to build the temples that has allowed them to endure for thousands of years. Recently restored, the site is visitor-friendly with walkways and a new center with displays of prehistoric artifacts from across Gozo.
