Lyneham Longbarrow is a long barrow near Lyneham, Oxfordshire. It is beside the A361 road, between Shipton-under-Wychwood and Chipping Norton. Just nine metres from the barrow mound stands a 1.8 metre tall standing stone.
Lyneham barrow stands on a ridge overlooking valleys to the northwest and southeast.[1] The long barrow mound is 52 metres long, 19 metres wide and stands up to 1.75 metres high.[1] Next to it is a weathered sandstone megalith 1.8 metres in height above ground level, 2.0 metres in width and 0.5 metres thick.[1] The stone may have been part of a facade of standing stones.[1]
The barrow was excavated in 1894. The excavations located two chambers on the southeast side of the mound and at least one of these contained bone fragments, pottery and charcoal.[1] Also found were two Anglo-Saxon burials which had been cut into the top of the existing mound.[1]
