Castlerigg Stone Circle, in the English Lake District. The Neolithic stone circle is thought to have been constructed in around 3000 BC, and is potentially one of the earliest in the country. The monument includes an oval enclosure of stones which contains a smaller enclosure and two barrows, and an outlying stone. The oval enclosure includes 38 large stones, some standing up to 3m high and some fallen, and 3 smaller stones; it encloses an area measuring approximately 32m north-south by 29m east-west. Castlerigg Stone Circle remains unencumbered by modern development, and is one of the finest examples of a large irregular stone circle in England. https://historicengland.org.uk/listing/the-list/list-entry/1011362 The model was created from 455 photographs.
