📜 History of Longest Day (Summer Solstice)

The dates of the agricultural cycles were tied to the summer solstice in the Neolithic societies of Northern and Central Europe. It was historically observed by lighting bonfires to increase the sun’s strength throughout the agricultural season and guarantee a bountiful harvest in the Celtic, Slavic, and Germanic civilizations.

It appears that many Neolithic stone circles were built to follow the Sun’s path during solstices. However, it is challenging to pinpoint the precise function of these rock structures because there are no recorded reports from this era. However, the stones also seem to have been placed with care to line up with the Sun’s arcs, framing solar motion during the summer and winter solstices.

Even hammerstones were placed at particular solstice axes to frame the dawn for those standing in the center of the circle. This shows that the stones’ alignment with the sun’s movements was deliberate. Many tribes in the past and some tribes today still celebrate the summer solstice as a big cultural event.
