A late Neolithic henge enclosure in the valley of the River Avon northwest of Stonehenge dated to the middle part of the 3rd millennium bc. Excavations by Geoffrey Wainwright in 1966–8 showed that it comprised a large sub‐oval banked enclosure over 450 m across with an external bank and internal ditch. There were two opposed entrances, the one to the southeast providing access to the river. Inside, the excavations revealed a series of massive circular timber structures represented by postholes. The two examined had both been rebuilt several times over the same spot. The excavator suggests that these were large roofed structures, but other interpretations are possible. Finds included much grooved ware pottery. The animal bones indicate that many pigs were consumed on the site, and it has been suggested that feasting was one of the main activities carried out at the largest of the two structures investigated.
