Caption: The Heel Stone of Stonehenge.

On the summer solstice, the Sun rises over Heel Stone as seen from the center of Stonehenge where is located the Altar Stone. The summer solstice is on or about June 21 and is the start of summer.

The structure to the left could be a portable---which just goes to show how advanced were the Stonehengers (AKA Neolithic Britons).
