Seahenge, known as Holme I, was a monument located in the village of Holme-next-the-sea. An upturned tree stump is placed in the center and 55 small split oak trunks surround it, making up circular enclosure. Although no one knows exactly why the site was built, there is a belief that it is related to a rite to honor the dead.
The site dates back from 2049 BC. It is now being eroded gradually by tides.
