Adam's Grave was a Neolithic long barrow near Alton Barnes in Wiltshire, southwest England.
[2] These generally consist of long, precisely built trapezoidal earth mounds covering burial chambers, thus they are a type of chambered long barrow.
The chamber, made of sarsen stones, contained partial human skeletons.
[1] The area around Adam's Grave has a high density of long barrows and is important because of its archaeological potential.
According to folklore the barrow is the grave of a giant, and his ghost has been reported.
