The sale of this sprawling 80-room castle in the foothills of the Italian Alps will be an opportunity that only comes along once in seven lifetimes when it goes to auction next month.
Set in the picturesque Dolomite mountains, Castel Valer has belonged to the aristocratic Spaur family - whose family lineage includes the first Bishop of Vienna - since 1368.
Count and Countessa Spaur zu Flavon und Valer currently live in its 80 rooms, which are spread over 35,520 sq ft.
The castle is being sold fully furnished. It was previously valued at £26 million (€31 million) but it is set to go under the hammer without a reserve price.
There are 15 bedrooms, 14 bathrooms, five kitchens and two chapels inside the sprawling pile, plus the essentials - a wine cellar, sauna, library and pool.
Each room has been carefully restored over the past 20 years, preserving the 16th-century frescos and Romanesque, Gothic and Baroque architecture.
A dramatic 130ft-high central tower stands as tall as Rio de Janeiro's Christ the Redeemer (including the pedestal), and four times higher than the platform Tom Daley and Dan Goodfellow won bronze for synchronised diving at this year's Olympics.
The tower was built in 1180 by the Austrian Empire to guard the entrance to the Val di Non - a valley rich in lakes, villages and history.
The castle itself sits in 12 acres of forest, with six acres of apple orchards, and 'countless' terraced gardens. It is located about a two-hour drive from Verona or Venice, in the Dolomite mountains.
It has great earning potential as a hotel or B&B, and has previously been rented out for weddings and concerts.
