The selling agents suggest a short commute across the Atlantic
The sales pitch for a £5m luxury tower house in Caithness includes the suggestion that it is only a six-hour private jet flight from America.
Ackergill Tower also offers the chance to view the Aurora Borealis and killer whales in the Pentland Firth, according to estate agents Knight Frank.
Overlooking Sinclair's Bay, a website for the property describes it as an "exclusive retreat".
The house is three miles from Wick Airport.
On its website, Knight Frank said the surface of the sea below can be broken by the tail fin of a passing sea trout and residents may hear the alarm call of seals frightened by a pod of killer whales.
Among the details on reaching Ackergill, the estate agents say: "As an ex-military base the strip at Wick Airport is suitable for almost all private jets and is just over a six hour flight from Hartford, Connecticut in the USA."
Dating from the 15th Century, the tower was extended in 1850 and later underwent restoration work.
John Coleman, of Knight Frank, said: "Ackergill is a very special place, the perfect retreat.
"Not surprisingly there has been strong interest which is being managed to ensure there is no disruption of the business during the sales process."
