New research suggests Stonehenge was built 5,000 years ago by a team of builders from Crymych who stopped work after the second instalment of their payment failed to arrive.
Archaeologists made the breakthrough after discovering a stone tablet marked “FINAL REMINDER” beneath what was previously believed to be a ceremonial burial mound.

Artist’s impression: roof, windows and second instalment still outstanding.
“It was actually where they emptied the van,” explained lead researcher Dr Ceri Thomas.
“We found broken tools, several lunch containers and a quote for patio doors.”
The discovery explains why the monument has neither a roof nor windows.
“We’re still owed for the lintels.”
A message attributed to site foreman Cai Carreg makes the builders’ position clear.
“We’ve done what we’ve been paid for. The boys won’t be back until the balance is settled. You can organise as many solstices as you like.”
Researchers believe the customer had withheld payment because the entrance was supposed to face the other way.
English Heritage hopes to complete the work once it finds a builder who can start this side of Christmas 2035.
“One chap has looked at the photographs,” said a spokesperson. “He asked what cowboy put it up, sucked his teeth and said it would all have to come down.”
