Aye, and given both the weight and the sticky-out roots of the stump, hauling it overland from A to B must have been no mean achievement (there’s a hole in the stump where it’s thought ropes were threaded through and used in the hauling process). There’s so little stone in this neck of the woods (East Anglia) that such a well preserved wooden circle really does hit you hard.

Interestingly, you see something very similar at the Anglo-Saxon church at Greensted where oak logs have been hewn in half – again with the flat side in and the round side out. More than two and a half thousand years separate Seahenge from Greensted yet the structural similarities are uncannily similar.
