From the top floor Glenapp Castle in Ayrshire, Scotland, you can gaze out to the sea and spot the granite islet Ailsa Craig, the Isle of Arran, the Mull of Kintyre and, on the clearest of days, Ireland. It’s quite the spectacle from what is now the 420sq m penthouse, The Endeavour. Comprising four bedrooms, four bathrooms, a lounge and dining room, sauna, library, games room and massage room, the expansive setting – formerly the quarters of the First Lord of Inchcape, once the chairman of the Peninsular and Oriental Steam Navigation Company, better known as P&O – is an ode to the Scottish coast and its maritime history. The decor mixes traditional furnishings with modern touches, which is bolstered by an array of classic artworks and artefacts. Of course, rounding out a stay in The Endeavour is special access castle’s grounds and attractions – and, particularly for you, exclusive entrance to its roof and ramparts.
