England has many ancient and mysterious phenomena in addition to the crop circle formations.
One of the most famous is Stonehenge, estimated age 3100 BC.
Another which I personally find fascinating is the stone circles at Avebury, argued to be the most impressive of all remaining prehistoric earthworks in Europe, age 2400BC. (To give a perspective on size, the blue spot on left is Chas walking through the stones)
Then there is Silbury Hill, the tallest prehistoric human-made mound in Europe and one of the largest in the world. It is similar in size to some of the smaller Egyptian pyramids. This is part of the complex of Neolithic monuments around Avebury, which includes the Avebury Ring and West Kennet Long Barrow.
Another is Wayland's Smithy long barrow - a large chambered Neolithic tomb. Excavations in 1962-63 proved that it had been built in two different periods, around 3700 and 3400 BC.
There are also the famous white horses - at least 24 of them. Most of them are chalk hill carvings with many of them in the Wiltshire area. Most of them date from the last three hundred years or so, though the origins of some are impossible to establish with any certainty. Only the Uffington white horse is of certain prehistoric origin, being some three thousand years old. This stylised prehistoric hill figure, 374 feet (110 m) long, formed from deep trenches filled with crushed white chalk on a very steep hillside. One wonders how it was created. Wayland's Smith is only a couple of miles of the Uffington White Horse. To see a full image of the horse log on to http://en.wikipedia.org/wiki/Uffington_White_Horse. Very impressive.
These images are only the few that I have seen. There are many more. These sites are maintained and preserved by Britain's National Trust, and some are World Heritage listed.
Some believe that there is a connection between the geometrical placement of stone circles and the geometry found in the crop formations.
