National Treasure: The search for the Sancy Diamond

Somewhere in Cliveden’s woodland there's a lost treasure waiting to be discovered. Band together to solve the clues and see if you can solve the case of the missing Sancy diamond.

  • Booking not needed
  • Admission applies

Back in 1946 during a lavish dinner party, the Sancy diamond from Nancy Astor’s bejewelled tiara was stolen. The criminals hid the stolen diamond in the woodlands and left instructions for an accomplice to collect it at a later date, but during their escape they dropped the clue sheet and so never returned to collect their plunder. Decades later, these instructions have been rediscovered and now it’s your turn to try crack the codes and find Nancy’s Sancy diamond.

What is Gift Aid?

Most of our places run the Gift Aid on Entry scheme at their admission points.

Under this scheme, if you're not a member you have the choice of two entry tickets:

  • Gift Aid Admission
  • Standard Admission

If the place runs Gift Aid on Entry, we'll offer you a clear choice between the Gift Aid Admission prices and the Standard Admission prices at the admission point. It's entirely up to you which ticket you choose.

Gift Aid Admission includes a 10 per cent or more voluntary donation. Gift Aid Admissions let us reclaim tax on the whole amount paid - an extra 25 per cent - potentially a very significant boost to our places' funds.

An extra £1 paid under the scheme can be worth over £3 to the National Trust as shown below:

  Gift Aid Standard
Amount paid by visitor £11.00 £10.00
Tax refund from Government* £2.75 £0.00
Total received by the National Trust £13.75 £10.00
