Police arrested 25 people at Stonehenge overnight after an estimated 37,000 people saw the sun rise on the longest day in the calendar.
Officers with Wiltshire Police said the arrests were largely for drugs-related offences.
The Summer Solstice has a long tradition of attracting people to monuments such as Stonehenge, off the A303, where latter-day Druids gather to witness the sun rising on the longest day.
A police spokesman said: "We are pleased that the Solstice celebrations at Stonehenge and Avebury have been enjoyable events for the majority of people attending.
"There were 25 arrests at Stonehenge and two at Avebury which were mainly for drug-related offences."
