Two Just Stop Oil protesters sprayed orange powder paint over Stonehenge on Wednesday. As the two protesters sprayed the site’s stones, tourists viewing the monument attempted to physically restrain them. This occurred the day before the summer solstice, an important day marked by large crowds gathering at Stonehenge. By pulling this kind of stunt, Just Stop Oil has defaced a vital piece of our human heritage and only harmed its own political movement.

Stonehenge’s initial construction began over 5,000 years ago, in about 3700 BC. There is evidence of human use and construction continuously over the next 2,000 years. Neolithic workers dragged some of Stonehenge’s megalithic stones more than 150 miles from their quarries. Though its original use is debated by historians and archaeologists, many graves important to research have been found at the site.
