English Heritage looks after Stonehenge on behalf of the nation. But we do not control the copyright of all images of Stonehenge. And we have never tried to do so.
We have no problem with photographers sharing images of Stonehenge on Flickr and similar not-for-profit image websites. We encourage visitors to the monument to take their own photographs. If a commercial photographer enters the land within our care with the intention of taking a photograph of the monument for financial gain, we ask that they pay a fee and abide by certain conditions. English Heritage is a non-profit making organisation and this fee helps preserve and protect Stonehenge for the benefit of future generations. The majority of commercial photographers respect this position and normally request permission in advance of visiting. We regret the confusion caused by a recent email sent to a picture library.
