Want to live like in Downton Abbey: Avail a spare £2.5million
According to the Daily Telegraph, all of the properties are currently being advertised by British estate agents and range from a historic Scottish fortress that once belonged to the earls of Fife to a magnificent hilltop palazzo in Italy.
But you'll need deep pockets to afford one, as even the cheapest of the palatial homes will set you back more than £1 million.
Historic: Parts of the magnificent Castello di Collalto just outside Rome date from the 10th century but if you want to move in, you'll have to cough up more than £7m
Spacious: The nine-bedroom castle sleeps up to 19 people and also boasts seven bathrooms and a separate two-bedroom cottage for staff
Spectacular: The 14th century Thurland Castle has been converted into a number of luxury apartments. The three bedroom Cromwell Wing is yours for £1.1m
Renovated: The two main rooms in the Cromwell Wing are of vast mediaeval proportions and have retained their original fireplaces and cornice fittings
Each of the castle dates from a different period, although Westenhanger Castle, near Hythe in Kent, arguably has the most fascinating past.
The castle, a scheduled ancient monument, began life in 1035 during a period of Danish rule under King Canute. Following the Norman Conquest, Westenhanger was passed to a succession of knightly families, including the de Aubervilles, the de Kiriols, the Fogges and the Poynings.
Permission to crenellate was given by Edward III in 1343 and a curtain wall built to connect with the earlier round tower. By the 1540s, the castle was crumbling and it was completely remodelled by its Elizabethan owner, Thomas Smythe, in 1581.
Impressive though Westenhanger is, it isn't the only castle with a history to be proud of on sale. Thurland Castle in Lancashire, although split into several apartments, still retains its moat and was owned by Sir Bryan Tunstall, a heroic soldier immortalised in a poem by Sir William Raleigh.
He was a hero of the Battle of Flodden in 1513, and was dubbed the 'Stainless Knight' by King Henry VII. He was followed by his son Marmaduke, who became High Sheriff of Lancashire.
Magnificent: The 16th Century Lickleyhead Castle in Auchleven near Aberdeen was built in 1560 by William Leith and boasts seven bedrooms and seven bathrooms
Imposing: The drawing room at Lickleyhead Castle, which despite it's vast size, is the cheapest of the castles and costs just £1.3m for the entire property
Cosy: Despite it's impressive size, Lickleyhead Castle is cosily furnished with traditional dark wood in the library (left) and romantic four poster beds (right)
Striking: The cream stone Myres Castle near St Andrews comes with two additional properties and has 10 bedrooms, a library, a Victorian kitchen and a billiards room
Comfortable: Myres Castle was begun in 1454 and was the ancestral home of the earls of Fife. It's now on the market at £2.5m
Later, Thurland was sold to Sir John Girlington, who fought on the Royalist side during the English Civil War. During a 1643 siege, the castle was badly damaged by Parliamentarian forces and was left in a 'ruinous' condition before being restored in the 18th century.
But not all of the homes are in England. Scotland too has a wealth of impressive properties including the pretty 18th century Bonaly Tower, which was the venue for frequent meetings of the 'Friday Club', a group of leading Edinburgh literati, hosted by owner Lord Cockburn.
Others include Myres Castle near St Andrews, the former seat of the earls of Fife, and the imposing Lickleyhead Castle near Aberdeen, which was built by William Leith in 1560.
Outside of the UK, there's a magnificent Italian palazzo dating from the 10th century. But the Castello di Collato near Rome doesn't come cheap. Of all the properties, it is the most expensive and you'll have to hand over £7 million before you get to move in and become king of the castle.
Heritage: Castle Gogar is just six miles from the centre of Edinburgh and was built in Scots Baronial style. It has seven bedrooms and is on the market for £2.9m
Eclectic: Castle Gogar has its own battlements, towers and turrets within, while outside, the property boasts a menage and a stable block with room for three horses
Ancient: Westenhanger Castle in Kent dates from 1035 and the reign of King Canute but was modernised during the reign of Elizabeth II. It is on the market for £2.6m
Elizabethan: Most of the interior owes its shape and size to the first Elizabethan Age and includes period diamond-paned windows and inglenook fireplaces
Famous: The 18th century Bonaly Tower was the venue for frequent meetings of the 'Friday Club', a group of leading Edinburgh literati, hosted by owner Lord Cockburn
Sumptuous: A three-bedroom apartment within Bonaly Tower is on the market at £795,000 and includes a separate study and a slice of the extensive grounds
Deepdene in Surrey was once one of the grandest mansions in Britain. Seat of the Howards, the Dukes of Norfolk, from 1483 to 1797, the sprawling estate was surrounded by ornamental Italianate gardens, resplendent with orangeries, conservatories and terraces. But like so many other 'Downton Abbeys', this glorious example of our heritage is no more. In its place today stands a Kuoni Travel office block - and the grounds have now given way to the Dorking bypass. The story of Britain's lost stately homes has been recorded for posterity in a new book that documents the demise of dozens of our country's grand estates.

Nearly a third of the nation's magnificent mansions have perished over the decades due to world wars, death duties and changing social landscape.
Author John Martin Robinson has logged examples of our once-great houses that have become increasingly of interest due to TV costume dramas such as Downton Abbey and Upstairs Downstairs.
His new book includes photos of the grand residences, landscaped grounds and the families and staff who lived and worked in them and shows what life was like in this other world.
Cassiobury in Hertfordshire. Demolished in 1927, it has now been swallowed by the urban sprawl of Watford
Cassiobury estate workers on the river Gade in Hertfordshire. Urban sprawl was a factor in the loss of many homes, especially in areas of great industrial expansion
In 1909, the 8th Earl of Essex sold off 184 acres of Cassiobury's parkland - mostly to Watford Borough Council. The grounds where the estate once stood are now bordered by housing
Since World War II, about 1,000 country houses have been demolished across the country.
Others have been turned into flats or have diversified in other ways, but are a far cry from their heyday.
And one badly advised or headstrong member of a family was perfectly capable of ending hundreds of years of traditions. Examples in the book include Beaudesert in Staffordshire, the seat of the Pagets, Earls of Uxbridge and Marquesses of Anglesey from 1546 to 1935.
Henry Paget, the 5th Marquess of Anglesey - known as 'Toppy' - squandered his inheritance in the late 19th century.
Known as the 'Dancing Marquess' for his snake-like dances, he became bankrupt in 1904 - and partly as a result of his excess, the family home was broken up and sold off.
This family had two estates and, after selling off Beaudesert, moved to the more rural one in Anglesey.

Cassiobury in Hertfordshire, seat of the Capels, Earls of Essex from 1546 to 1922, suffered partly because it was consumed by Watford.

The demise of Lathom, the finest Palladian house in Lancashire, in 1925 was 'swift and destructive'.
Mr Robinson wrote that it was 'entirely due to the unsatisfactory character of the 3rd and last Earl of Lathom, a theatrically obsessed chum of Noel Coward, who failed to produce a son and sold up'.
Shillinglee Park in Sussex had its own cricket ground where W.G. Grace played alongside Indian nobleman Ranjitsinji.
The 4th and 5th Earls of Winterton founded Sussex County Cricket Club, but the family home was gutted by fire when Canadian troops were staying there during the war.
After being restored in 1975, it was converted into three large private apartments.
The book, Felling The Ancient Oaks, has over 20 examples of country estates that are no more.
Also mentioned is Costessey, in Norfolk. It was the seat of the Jerninghams for nearly 400 years until being demolished in 1925, after being requisitioned during WWI. The former estate has now been swallowed up by Norwich. Mr Robinson said: 'In the book, I have tried to give a geographical spread of estates for which there were also good photographs. 'The problems for these estates really started in the 1870s with the agricultural depression. Many of the estates, especially the smaller ones, were based on farming.
'Until the 1870s, we fed our own population and exported food, but then we became overwhelmed with grain from places like Canada.
'Grain from abroad was half the price and there was no protection for the farming industry.

'And then when refrigerated ships were introduced, we could import meat from around the globe.' He added: 'Farming in England had been profitable since the 1660s and when the agricultural depression came, it was a great shock. 'The Liberals in the late 19th century also wanted to introduce land reforms, to tax land and make compulsory purchases.
'Many people felt it was time to sell up. Then in the 1890s, death duties were introduced and these got as high as 80 per cent in the 1950s.

'In the 19th century, estates were generally sold to another family but in the 20th century they were broken up. They were essentially stripped of their assets.
'In the first three quarters of the 20th century, these estates were worth more dead than alive.
'Other factors included the wars when taxes were raised to pay for them - and some families died out when sons were killed.

'Urban sprawl has also been a factor especially between the wars when there was no planning laws.
'And there are always some individuals from a family who are responsible for the loss of the estate through personal incompetence - through gambling for example.
'After the war, planning restrictions and the National Trust meant that many were saved. And with farming coming back, people are starting to buy estates again.'
When the largest home in Wisconsin went to auction last year, its sellers must have thought they had a real zinger on their hands.
But fast forward 12 months, and Ellison Bay Manor, in picturesque Door County, is still on the market.
Perhaps given the state of the sluggish US economy, an $8.75million (£5.4m) price tag is too much for even the wealthiest prospective buyers.
For that money, they'd get a mansion with three grand guest suites, 10 bathrooms, and a massive 5,000sq ft master suite.
Larger than the average American home, the master suite alone has two dressing rooms, two bathrooms, a sitting room and a fitness room - which can even be reached by elevator.

Last October, the 43-room property - which has been empty for almost a decade - was known as Sur la Baie and was put up for sale for $19m
The 35,000 sq ft French-inspired estate, built by Chicago philanthropist Judith Blazer in 1993, is one of the largest single-family residences in the state

Last October, the 43-room property - which has been empty for almost a decade - was known as Sur la Baie and was put up for sale for $19million.
But clearly its new name has not been enough to entice a new owner.
'We had at least half a dozen offers. 'We had some who were fairly interested and basically they indicated that it was really a full-time residence, it was not really a vacation type property and they were not prepared to live year-round in Door,' realtor Kurt Penn told Fox 11.

Ellison Bay Manor is currently owned by realty group Jameson Sotheby International Realty, based in Chicago - who have managed the property for six years
The house even has its own big screen movie theater complete with concessions stand and ticket booth
The house also features sitting rooms, an entire wing dedicated to a pool and spa including tropical plants, and a floor made of Jerusalem quarry stone
The house was sold to an unnamed couple from California in 2005, but the pair became ill before they could move in and never lived there
Blazer built the house to mimic 19th century homes on the East Coast.

Ellison Bay Manor is currently owned by realty group Jameson Sotheby International Realty, based in Chicago - who have managed the property for six years.
The new deal includes the beach house, guest house and 80 acres of land.
Penn said that the owners will pay the first five years of real estate tax, and will also donate 4 per cent of the sale proceeds to charities such as the Door County Humane Society, Midsummer Music Festival, the Medical College of Wisconsin, and another charity chosen by the buyer. Given the downturn in the real estate market since that 2005 sale, real estate agents expect buyers with enough cash on hand could make a killing on the sale. Last year, Hilco Real Estate Michael Fine described the house as a mixture of classic style and modern amenities with a breathtaking view of Green Bay.

'Spiral staircase, leaded glass stained window,' Fine said. 'An entrance from the balcony above into the owner's bedroom.' The house also features a two-storey library designed in the style of the Vanderbilt mansion, sitting rooms, and an entire wing dedicated to a pool and spa including tropical plants, a floor made of Jerusalem quarry stone, and several waterfalls including one connecting to a 14-person whirlpool.
The indoor pool also includes its own fully-functional kitchen, guest locker room, steam shower and bathroom. The house even has its own big screen movie theater complete with concessions stand and ticket booth. Realtors told Fox that the problems in the housing market are not limited to shifting huge mansions. Less expensive holiday homes, such as another valued at around $1.5million has also proved hard to sell.
'This is probably an average upscale vacation home in Door County. It's been for sale this time for about seven months,' said Scott Bader, from Coldwell Banker.
'Right now I think there are only about 40 to 45 for sale. So that's a fairly long market time.'
Scott Bader, who specialises in homes valued at more than $1 million, said just seven such properties have been sold annually in the county.
Ellison Bay Manor has been rented out for private events but is classed as residential, so cannot be converted into a hotel.
