Europe's most beautiful castles
Pena National Palace in Portugal
Art historians often complain of this palace's unusual mix of eclectic styles, much in accordance with the exotic taste of the Romanticism - a combination that some regard as kitschy and even reminiscent of Disneyland. Tourists, however, love the palace in the town of Sintra. From the 14th century onwards, Pena Palace has been used by the Portuguese royal family as their summer residence.
