I visited Stonehenge in June 2013. I was lucky enough to enjoy some minutes of sunshine, although I think the grey clouds contribute to the overall ambience. The Neolithic remains are very similar to those of Malta, while the mounds or tumuli resemble those of Knowth in Ireland. Definitely a must see and once you go close to the stone circle you won't hear any noise pollution from the nearby highway so all in all a positive experience and another site off my bucket list :)
