While we were waiting for the sun to make its appearance on the occasion of the Spring Equinox, I wandered around some of the lower chambers of Mnajdra Temples. Its magnificent megaliths, over 4000 years old, had withstood the test of time and still stood mysteriosly on the rugged cliffside. Intense restoration is taking place at the moment to combat erosion from modern pollution which would eventually deteriorate the stone structures if not taken care of. Scientific measurements of humidity and temperatures amongst others are being conducted to evaluate the situation.
