Maumbury Rings were excavated by Harold St George Gray from 1908–1913.
The excavations showed that the site originated in the later Neolithic period.
The excavations revealed an internal ditch which comprised a series of deep shafts cut into the chalk.
These number up to 45, and were up to 11 metres deep.
Eight shafts were fully excavated.
They contained various deposits including antler, animal and human bone, flints and carved chalk.
A single Grooved ware pottery sherd was recovered from one pit, and a later Beaker sherd was recovered from the fill of another pit.
The henge had a single entrance on the northeast side.
It is recorded that a large stone was discovered during cultivation in 1849 to the west of the entrance, but it was reburied and has not been seen since.

Around 2 km due east are the faint traces of a larger henge known as Mount Pleasant henge, and archaeology has revealed the presence of another Neolithic enclosure known as Flagstones near there.
In addition, when archaeologists were digging on the site of the Tudor Arcade/Waitrose development in the 1980s (around 800 metres northeast of Maumbury Rings) they discovered large timber postholes.
The evidence suggests that they were part of a large Neolithic enclosure with a diameter of around 300 to 400 metres.
Red markings, denoting sites of some of the timber posts, can be seen in the car park of Waitrose.
