These former military barracks where a ‘Dad’s Army’ actor served have hit the market in a rare property sale .

The Defensible Barracks, in Pembroke Dock, were originally built for the Royal Marines in the early 1840s and have a long and rich history.

The historic building is on Barracks Hill and has housed famous residents since its construction, such as ‘Dad’s Army’ actor Arthur Lowe - who played Captain Mainwaring - and Crimean War hero Gordon  of Khartoum.

As one of the best-preserved bastions in Europe, the 20-sided fort spanning 50,000 square feet features a parade ground, VR crests, Prince of Wales feathers and canon batteries.

Set over three floors, the barracks surround the parade grounds, and used to provide accommodation for approximately 100 soldiers.

The Grade II* listed barracks are being marketed with Strutt & Parker, with a guide price of £500,000 - working out to £10 per square foot.

Gary Haskell, Head of New Homes (Midlands) at Strutt & Parker, commented: “The rarity of such a historical building coming to the market, and one with such exciting potential, means we have immediately seen interest from developers who want to return the Barracks to their former glory.

“Whether it’s transformed into residential homes or a hotel, the project will inject investment into the area and bring new people to Pembroke Dock.

“Whilst the fort was originally centred on defence, it was also home to hundreds of military personnel in its 100+ year history and whilst a lot of work is now required, it still has a real sense of liveability – the potential of which is already proving attractive to those with the imagination.”

On the location, Joe Martin, Senior Associate Director at Strutt & Parker, said: “Thanks to its incredible scenery and heritage, Pembrokeshire is continuing to attract people, both from the surrounding regions and further afield.

“The coast and beaches at Stackpole and Freshwater East & West are hugely popular, and are just over five miles from the Defensible Barracks, whilst Pembrokeshire National Park is on your doorstep.

“Pembroke town itself is also the subject of a multi-million-pound regeneration scheme which will no doubt bring the area further into the spotlight.”
