About 20,000 people crowded the prehistoric monument on Salisbury Plain, southern England, to see the sunrise at 4:52 a.m. local time, following an annual all-night party.
The event typically draws thousands of alternative-minded revelers to the monument, as they wait for dawn at the Heel Stone, a pockmarked pillar just outside the circle proper, which aligns with the rising sun.
Unlike previous recent years, when the sunrise has been obscured by cloud - the bright sun bathed the monument in orange and gold on Monday.
"One time in maybe 10 we get a decent sunrise, and that was a good one," said Simon Banton, a 45-year-old education volunteer for English Heritage, the body that manages the site.
As the sun rose, a woman climbed a rock in the circle center and blew a horn, welcoming in the longest day of the year north of the equator. Drums, tambourines, and cheers reverberated in the background.
"It means a lot to us ... being British and following our pagan roots," said Victoria Campbell, who watched on, wearing a pair of white angel's wings and had a mass of multicolored flowers in her hair. The 29-year-old Londoner, who works in the finance industry, also said that "getting away from the city" was a major draw.
"It is stunning," said Stewart Dyer, a 43-year-old National Health Service worker and dancer on his first trip to the solstice celebration. "To actually be able to dance amongst the stones, to be able to touch the stones, to be that close to such an ancient monument is unbelievable."
The annual celebrations at Stonehenge, about 80 miles southwest of the capital, are a modern twist on solstice celebrations which were once a highlight of the pre-Christian calendar. They survive today largely in the form of bonfires, maypole dances and courtship rituals.
Andy Barrett, a 62-year-old restaurant owner from Kent, said he has been coming to solstice celebrations at Stonehenge for decades.
"It's amazing. The wonderful thing is all these people experiencing it and wondering what this was all for trying to work out in their own minds - what was it all?" he said.
Stonehenge's origins remain a mystery, but theories suggest the grounds were part of a huge astronomical calendar. Others say an ancient sun worshipping culture aligned the structure with the midsummer sunrise and the midwinter sunset. The site was used as a cremation cemetery since its inception, archaeologists say, but it is unclear if that was its main function.
"The truthful answer is we don't know exactly what it was for," said Amanda Chadburn, an archaeologist with English Heritage, which manages the site.
Whatever its origins, the construction of Stonehenge - built with massive stones drawn from up to 150 miles away - gives insight into an ancient culture, Chadburn said.
The World Heritage site was built in three phases between 3000 B.C. and 1600 B.C. It is one of Britain's most popular tourist attractions with more than 850,000 visitors a year. The solstice is one of the few times access is granted inside the stone circle, which has been roped off since 1978, following years of erosion and vandalism.
Police said Monday they had made 34 arrests, the majority for drug possession, and reported no serious problems.
