Stonehenge’s astronomical alignment remains one of its most remarkable features. During the summer solstice, the sun rises precisely over the Heel Stone and casts its rays into the center of the stone circle. And on the winter solstice, the sun sets in the exact same place. This suggests that our Neolithic ancestors built Stonehenge as a celestial observatory or a calendar. While nothing is confirmed, there are more theories about how the rest of the stones may have been positioned to align as an astronomical calandar.
This celestial significance has survived throughout the years. Today, thousands flock to Stonehenge to celebrate summer and winter solstice events. Many see it as a pilgrimage, and come to perform rituals, sing songs and dance together all night until the sunrise.
