Castlerigg stone circle

Castlerigg Stone Circle is on the level top of a low hill. There are 38 stones in a circle approximately 30 metres in diameter. Within the ring is a rectangle of a further 10 standing stones. The tallest stone is 2.3 metres high. It was probably built around 3000 BC - the beginning of the later Neolithic Period - and is one of the earliest stone circles in Britain. It is important in terms of megalithic astronomy and geometry, as the construction contains significant astronomical alignments. Photo by Laurenz Bobke
