3. 2 Bedroom Castle in Broadstairs, Kent, UK for £500,000

This fabulous duplex flat was once owned by professional golfer Nick Faldo.

It is set within the Grade II listed Kingsgate Castle and sits high above Kingsgate and Joss Bays.

It's also a home full of secrets.

See if you can spot the hidden cupboards in the wood panelling of the hallway ...... Or the smuggling tunnels in the courtyard.

(It turns out that in Georgian times it was a popular place for such secret activities).

We loved the lush oak panelling in the lounge and kitchen/dining room, and the beautiful circular bedrooms in the tower.

The new owners will also enjoy the extensive communal lawns and manicured lawns, ideal for after dinner walks.

4. 2 Bedroom Castle Apartment in Penzance, Cornwall for £500,000

Fancy a whole wing of a castle?

Acton Castle dates back to 1775 and was built by the famous marine botanist John Stackhouse so he could study the bay below.

The castle is an outstanding example of skilled stone masonry and was converted into a handful of luxury flats in the 1990s.

Famous smuggler John Carter, known as 'The King of Prussia', used to live here because of its proximity to Prussia Cove, where large quantities of contraband were once disembarked.

Local legend has it that tunnels in the castle lead to the cove below.

In the huge open-plan living/kitchen-dining room, you can enjoy the stunning sea and coastal views through the marble-studded windows.

You can also stroll through the beautifully landscaped gardens, which provide direct access to the coastal footpath to nearby Marazion and Perranuthnoe.
