Eight of the best castles for sale around the world

In the Sherlock Holmes novel The Valley of Fear, John Douglas finds himself fleeing some of the most dangerous men in America. On arrival in England, his first move is to invest in a fortified property, complete with a moat and a drawbridge, from which to defend himself.

Back in the real world, the factors of privacy and security are still an important part of a castle’s appeal, but buyers also yearn for the romance of owning a home that has survived — or, indeed, played a role in—hundreds or even thousands of years of history.

Happily, these properties aren’t only ideal for keeping people at bay, they also lend themselves to entertaining on a grand scale. And there’s always the comfort that, should one attract the attention of an evil secret society, the perfect hideout has already been arranged.

Quinta do Marquês was originally constructed in the 17th century, but extensive renovations were carried out two centuries later under the guidance of its illustrious owners, the Counts of Foz.

On the ground floor sits a suite of palatial reception rooms, designed for large-scale entertaining, and outside are extensive landscaped gardens, a chapel and a swimming pool.

With wonderful vaulted ceilings, timber floors and a highly unusual 17th-century overmantel, Killahara is imbued with drama and romance. (00 353 87 246 3748; www.premierpropertiesireland.com)
