Seahenge was an archaeological discovery made in 1998 off the Norfolk coast in England. It consisted of a circle of vertically embedded wooden planks surrounding a large inverted oak tree stump in the center, dating back to around 2020 BC. Its purpose is unknown but theories suggest it may have been used as an inverted oak stump-altar, excarnation platform, or to symbolically mark a boundary between two worlds given its coastal location.

• Inversion: ie everyday objects upturned during
the Bronze Age
– symbolises taking objects out of this world and
placing them in the next
• Inverted oak stump-altar? Excarnation
platform?
• Symbolic location on coast-”Between 2
worlds”?
• Or, simply to mark a boundary?

5. One of the most haunting and enigmatic
archaeological discoveries of recent times was
the uncovering in 1998 at low tide of the so-
called Seahenge off the north coast of Norfolk.
This circle of wooden planks set vertically in
the sand, with a large inverted tree-trunk in
the middle, likened to a ghostly ‘hand
reaching up from the underworld’, has now
been dated back to around 2020 BC. The
timbers are currently (and controversially) in
the author’s safekeeping at Flag Fen.
