The sunrise of the first day of the four seasons enters into the Southern temple of Mnajdra and lights up the interior of the building. The ray of sunlight on summer solstice, lights up the edge of a megalith on the left of the entrance chamber. Likewise, on the winter solstice, the sunbeam arrives on a twin megalith on the right of the entrance chamber. On the Equinox days the sunlight goes into the temple and its beam lights up the main axis of the temple.

See the way the beams of sunlight at sunrise, enter into the Mnajdra Temple, during the yearly cycle of the four seasons.

See the yearly cycle of the rising sun over the hill opposite Mnajdra and the movement it makes along the horizon during the year.
