Could this be Kent's most expensive war building?

The historic Martello Tower, which was built in the 19th century to protect the British Empire from invasions, is located in a car park at Dymchurch, Romney Marsh.

The property had a guide price of £70,000 to £75,000.

But when it went under the hammer with Clive Emson earlier this afternoon, it fetched a staggering £145,000.

The 40ft forts were designed to hold 15 to 25 men.
