This material appears to have been brought from a variety of sources, much of it probably being generated outside the henge during the course of domestic routine.
The core of that landscape is a half mile circle centred on the henge.
They include villages, prehistoric settlements, new henges, foundations, mediaeval and early buildings, hill forts of the iron age, thousands of sites which are buried but very important.
A series of burials was dug into and around the henge enclosure.
Archaeological excavation of the central henge has taken place.
Super henge is sometimes used as a synonym for a henge enclosure.
The complex includes many large ancient structures including a cursus, henges, burial grounds and settlements.
The henge is surrounded by two ditches and a bank.
