A UK island complete with a five-bedroom home has hit the market for an eye-watering fee.
The private patch of land also boasts a helipad and rooftop bar and was historically used to repel a French invasion.
The property – a Grade II listed 19th-century fort – is located off the coast of Pembrokeshire and it could be yours for £3million.
But buyers will be rewarded with an eye-catching place to call home.
It boasts underfloor heating, mezzanine bedrooms, a sea-view office, and a 10-metre hydraulic crane for lifting boats and supplies and has been listed by estate agency Strutt & Parker.
“Thorne Island has been a landmark for hundreds of years,” the listing reads.
“The fort forming part of the Island was constructed between 1852 and 1854 as an outer defence to Milford Haven, at that time a large naval base.
“It is one of twelve forts that were constructed around the entrance to Pembroke Dock as part of ‘Palmerston’s Haven defences’ to protect against Napoleonic invasion.
“The Island was sold for the first time in 1932 and has since been a hotel and a family home.
“Thorne Island is a fantastic coastal landmark now offering something very different.”
The island sits a short three mile by sea from Milford Haven in south-west Wales.
It can be reached either by boat or helicopter depending on your budget.
The listing adds: “Upon entering the property through the historic entrance gates, you are welcomed into [the] entrance hall leading into the large open plan reception, dining and sitting room with exposed traditional brickwork, vaulted ceilings, double aspect sash windows and wood burning stove.
“The kitchen is open plan with a modern, equipped kitchen and adjoining snug with wood-burning stove, exposed brick work and sea views.”
“Outside is a courtyard laid to lawn, providing a sheltered entertaining space with adjoining storage rooms.
“Steps lead to the elevated grounds of the island which is home to the helipad and roof-top bar with inbuilt bar and games room.”
The property’s current owner, Mile Conner, bought the island in 2017, after watching a video about it.
He has mostly used the island for parties, and told Bloomberg: “Thorne’s been a great stress reliever.
“It’s just somewhere to go on boats and play with a crane and generators and fix stuff.”
If Thorne Island is out of your budget, then a picturesque private island off the coast of the UK is also available to buy – and it’s just £108,000.
The stunning Irish Islands of Dunnyneill, located on Strangford Lough, are home to range of gorgeous flora and fauna.
Surrounded by blue waters and coated in lush greenery, the islands are located just 2.5 kilometres off the coast of Killyleagh, Ireland.
Comprised of two islands, it was once a former seventh century trading emporium frequented by merchants.
Owning the islands gives you the chance to buy a piece of history, as merchants from Russia, Germany, Iceland and France used to visit the island.
The main island is described as being “formed from a small drumlin with a boulder clay core.”
