Solstice events at Stonehenge are some of the rare occasions when visitors are allowed to get close to the stones at the World Heritage site, which was built to align with the sun on the solstices.
Solstices are believed to have been celebrated at Stonehenge for thousands of years.
The summer solstice sees the sun rise behind the Heel Stone, the ancient entrance to the Stone Circle, with rays of sunlight being channelled into the centre of the monument.
It takes place as one of the Earth's poles reaches its maximum tilt towards the sun as it reaches its highest position in the sky, giving the longest period of daylight for the year and signifying the end of spring.
