The Heel stone, also known as the "Friar's Heel" or "Sun stone," is a single large sarsen stone standing outside of the main circle of Stonehenge. It measures approximately 6 meters in circumference and is 4 meters high.
The Heel stone has a significant relationship with the other stones in the monument. It is positioned so that it aligns with the main axis of the Stonehenge site. During the spring and autumn equinoxes, the sun rises in line with the Heel stone, casting its first rays upon the altar stone inside the Stonehenge circle. This alignment suggests that the ancient builders intended for this stone to mark the equinoxes and potentially other celestial events.
It is believed that the builders chose the Heel stone for its size and shape, as well as its relative isolation from the other stones in the monument. By aligning the Heel stone with the main axis of Stonehenge, they created a focal point for the site that would have allowed them to track the movements of the sun and potentially other celestial bodies. The precise alignment of the Heel stone with the equinoxes also supports the idea that the builders had a deep understanding of astronomy and may have used the monument as a tool for predicting and observing celestial events.
