The Solstice occurs on the 21st June every year, and what better way to experience the Equinox than at the Mnajdra Temples and Hagar Qim. The infamous UNESCO heritage sites are neolithic temples used by the worshipers to communicate with the gods.
The south temple is aligned with the position of the sun as it rises over the horizon on the first day of each of the four seasons of the year. It was purposely built in such a position so that the sun shines in between the stone at the Equinox and the Solstice. This used to help the people of the time to know when the seasons change and they need to harvest their crop.
