One of the most famous small islands in the UK has been put on the market – the price tag a cool £15million which includes an art deco hotel made famous by Agatha Christie.

Burgh Island off the Devon coast is a stunning location that is steeped in history, the tidal spot only able to be reached by sea tractor or by swimming when the tide is in. Built in 1929, the hotel provided a retreat for the novelist dubbed the queen of crime, who regularly stayed there, the location an inspiration while she wrote both Evil Under the Sun and And Then There Were None while a guest.

But now it’s been put up for sale by its company owners, the £15million getting you a Grade II Listed 25-room hotel, a nearby pub, the Pilchard Inn; in total, 21-acres of prime Devonshire land.

The sale is being arranged by Knight Frank, its website reading: “The private island setting is virtually unique in the UK and the hotel, which has been fully restored, is one of the finest examples of working Art Deco architecture in Europe.

“Burgh Island is a natural micro-environment, with wildlife to observe and cliff walks around the circumference. The sandy tidal beach on the eastern (mainland-facing) side is washed by the tide twice daily and so is always clean."

A circular glass skylight is one of the hotel’s numerous architectural features, and the inspirational setting was reported to have been used by Winston Churchill for a meeting with US military commander and later president, Dwight D. Eisenhower, in 1944 in the build up to D-Day. Other noted past guests include the Duke and Duchess of Windsor and in the 1960s the Beatles, ahead of a concert in nearby Plymouth.

But it was Agatha Christie who was most strongly associated with Burgh Island, so much so that it was used as a location for the TV adaptation of Evil Under The Sun, starring David Suchet as Hercule Poirot.
