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
