The mysterious monument of Stonehenge has stood without assistance for more than a millennium. It finally received a modern renovation — and the druids aren't happy about it.

The £27 million ($44 million) renovations by English Heritage include a new visitor center complete with a cafe, a virtual tour of the monument, and an extensive exhibition on the neolithic peoples who built Stonehenge around 5,000 years ago, reported the AP. The entire center is more than a mile away from the actual monument, meaning visitors must either walk or take a special shuttle to see the stones.

While the center itself poses no threat to Stonehenge and the druids that still gather there every summer and winter solstice, the bones that the center houses are a bit more problematic.

Led by senior druid King Arthur Pendragon, the druid protestors claimed that the three sets of bones that were excavated near Stonehenge and are being displayed in the visitors' center come from members of the royal line. Until the bones are reinterred, the druids plan to continue protesting.

"I don't want to give all my tactics away but next year's campaign will be based around the slogan 'don't pay, walk away', and encouraging people to make 2014 the year they did not come to Stonehenge," Pendragon told the BBC.

English Heritage, the group that raised money and built the new center, said it was important to use authentic relics to tell the story of England's history.

Built in three phases between 3000 B.C. and 1600 B.C., archaeologists are uncertain how the massive stones might have been used and which gods the ancient people might have worshipped. There is evidence that some of the stones came from 175 miles away and that large crowds gathered there for summer and winter solstices.

Recently, archaeologists discovered a neolithic village close to Stonehenge that contained evidence showing a "remarkable cultural interconnectedness" between the Britons of the era and the surrounding peoples in Scotland and France, said the Economist.
