The construction of the castle, which attracts 560,000 visitors a year, dates back to 1211, when the Teutonic Knights erected a fortress near the Eastern border of Transylvania.
The castle was completed in 1388, and was used as a fortress by soldiers attempting to stop the expansion of the Ottoman Empire. It also served as a customs base, holding goods that transferred in and out of Transylvania.
Irish writer Bram Stoker, who wrote the gothic horror novel 'Dracula' in 1897, took inspiration from descriptions of the castle to describe the home of Transylvanian Count Dracula, a centuries-old vampire and sorcerer who claims to be descended from Attila the Hun.
They are reportedly seeking new owners with the vision and financial means to carry out further renovation work, and one local told the Financial Times that they are rumored to be willing to consider offers of just 12 million euros ($13.4 million) for the castle.
