Stonehenge emerged as the most important free festival after the violent suppression of the Windsor Free Festival, in August 1974, and the lack of success in finding a permanent home for the People's Free Festival, after Watchfield 1975. 
By the beginning of the 20th century many of the bluestones were leaning precariously, probably due to the increase in curious visitors clambering on them during the nineteenth century.
Additionally two of the trilithons had fallen over during the modern era.
Three phases of conservation work were undertaken which righted unstable or fallen stones and carefully replaced them in their original positions using information from antiquarian drawings.
The first of the significant excavations at Stonehenge was led by Colonel William Hawley and his assistant Robert Newall after the site had come into state hands in 1918(see Deed of Gift of Stonehenge dated 26 October 1918).
He excavated portions of most of the features at Stonehenge and was the first to establish that it was a multi-phase site.
After the Second World War, the Universal Bond was permitted to re-commence its ceremonies although archaeologists such as Glyn Daniel and Stuart Piggott continued to campaign against what they saw as bogus Druidry throughout the 1950s, 60s and 70s.
In 1950 the Society of Antiquaries commissioned Richard Atkinson, Stuart Piggott and John FS Stone to carry out further excavations.
They recovered many cremations and developed the phasing that still dominates much of what is written about Stonehenge.
More recent minor excavations have been held to mitigate the effects of electrical cables, sewage pipes, and footpaths.
In 2005, excavations as part of the Stonehenge Riverside Project uncovered the remains of what may have been a village for workers or festival-goers near Stonehenge.
The site, next to Durrington Walls, about two miles from Stonehenge is also the location of a large timber monument.
The floors of several homes have since been discovered, as well as tools, animal bones, arrowheads and several more monuments.
The head of the project - Mike Parker Pearson - speculates that Stonehenge and Durrington Walls may have been connected by the nearby River Avon, as both monuments have Avenues which lead to the river.
He further considers it possible that the area around Stonehenge may have been the burial area for people living around Durrington Walls, and would have made up a 'Domain of the dead', whilst the village was in the 'Domain of the living'.
According to historical researcher Michelle Wilson, "What we have been looking at is a 20th Century landscape, which is reminiscent of what Stonehenge MIGHT have been like thousands of years ago.
It has been created by the heritage industry and is NOT the creation of prehistoric people.
What we saw at the Millennium is less than 50 years old."
Throughout the 20th century, Stonehenge began to be revived as a place of religious significance, this time by adherents of Neopagan and New Age beliefs, particularly the Neo-druids.
The historian Ronald Hutton would later remark that "it was a great, and potentially uncomfortable, irony that modern Druids had arrived at Stonehenge just as archaeologists were evicting the ancient Druids from it."
The first such Neo-druidic group to make use of the megalithic monument was the Ancient Order of Druids, who performed a mass initiation ceremony there in August 1905, in which they admitted 259 new members into their organisation.
This assembly was largely ridiculed in the press, who mocked the fact that the Neo-druids were dressed up in costumes consisting of white robes and fake beards.
Between 1972 and 1984, Stonehenge was the site of the Stonehenge Free Festival.
After the Battle of the Beanfield in 1985, this use of the site was stopped for several years and ritual use of Stonehenge is now heavily restricted.
Some Druids have arranged an assembling of monuments styled on Stonehenge in other parts of the world.
