Inchdrewer is owned these days by a prince no less. Count Robin Ian Evelyn Stuart de la Lanne Mirrlees of Inchdrewer, Baron of Inchdrewer and Laird of Bernera Mor (an island in the Outer Hebrides), was aid-de-camp to Peter II, last king of Yugoslavia, who as a token of his esteem, granted him the title Prince of Incoronata! Although an avowed anti-monarchist these days, the Count (his mother was a French Countess) has apparently started using his royal title recently.
He has led a 'dashing life' and it is said that Ian Fleming modelled the character of James Bond on him! (See note below) I presume the 'concrete' renovation work in Inchdrewer was done at the count's behest, however he is in his 80s now and spends most of his time on his estate in the Hebrides, which is why Inchdrewer is sadly starting to look its age yet again!
