In the heart of Transylvania, one of Europe's largest castles looks like it sits atop a rocky bluff with nothing but a thin bridge allowing access. But this is Corvin Castle, which looks like something straight out of a fairytale, largely because restorers thought that it should. 

Built in the mid-15th century, the castle was the work of military leader John Hunyadi, who constructed the tall structure over the remains of a keep built by Charles I.

Corvin Castle is split into three large areas: The Knight's Hall, the Diet Hall, and the circular stairways. Each of these three parts is surrounded by both circular and rectangular towers that were used for both defense and as a prison. 

The elaborate architecture was designed in a rich gothic style that accentuates the already impressive structure. The castle was kept in regal condition during Hunyadi's lifetime, but after he died, the castle fell into swift decline.

It was not until the 17th century that there was more interest in restoring this medieval castle. As the restoration work began, the workers redesigned the castle to reflect what they considered a gothic castle should look like, which explains much of its currently fanciful look.

A number of legends are associated with the castle. Though this is likely untrue, tourists are told that Vlad the Impaler spent some seven years in the dungeons of Corvin Castle, a stay which resulted in his eventual madness.
