Durrington Walls, overlooking the River Avon near Amesbury, is the largest known Neolithic henge in the United Kingdom.
Notes on verification
Confirmed by Historic England, Discovering Britain (RGS), and multiple independent tourism/archaeology sources. Minor nuance: some sources distinguish 'largest henge' from 'largest palisaded enclosure,' but the core claim about henge classification is well supported.
