The celebration is primarily the Celtic fire festivity, midsummer representing the center of summer, and also the shortening with the days on their own gradual drive to winter months. Midsummer is usually celebrated on either the 23rd as well as 24th of June, even though longest day actually comes on the Twenty-first of June. The importance of the day to our ancestors and forefathers can be tracked back thousands of a long time, and many natural stone circles as well as other ancient monuments are aligned to the sunrise in Midsummer's Day. Essentially the most famous positioning is that with Stonehenge, where the sun's rays rises on the heel natural stone, framed through the giant trilithons about Midsummer morning.
