Mystery photo: Where in the world is this Top Destination to see in 2013?

Deemed one of the best destinations to visit in 2013, according to Lonely Planet, for its “wonderfully preserved folk culture.” Skiing and hiking are currently the biggest draws to this relatively young country, specifically to the twenty mile mountain range running across the northern border which attracts serious skiers. But quieter countrysides with rolling hills and medieval villages are beginning to pop up on tourist itineraries too. Such as this walk, a slow saunter along trodden trails through meadows and fields where you might pass sheep and their shepherds or Gypsy children collecting wild blueberries on the way to a stunning castle built on the highest hill around.

For a small fee you can tour the museum and ruins of this large Gothic castle, a UNESCO World Heritage Site, which once protected area towns until the middle of the 18th century. Nowadays, it ranks as the top attraction in the country, and is frequently used as a location for films, including Dragonheart (1996), The Lion in Winter (2003), and The Last Legion (2006).  Where in the world is it?
