Often standing in for Castle Leoch on Starz network drama Outlander is the gorgeous Doune Castle, built in the 14th century no less!
One of the show’s leading stars, alongside actors Caitriona Balfe and Sam Heughan, is Doune Castle. It is frequently used as the exterior setting for fictional Castle Leoch, home to Clan Mackenzie and the initially imprisoned Claire Randall.The Perthshire castle was built in the 14th century and is home to one of the most well-preserved great halls in the country, as well as a 100-foot high gatehouse. It hasn’t always looked so handsome: by the turn of the 19th century, the castle had fallen into disrepair. The 14th Earl of Moray, George Stuart, began renovating the ruin in the 1880s to the extent that the castle is now one of Scotland’s most popular.
One Interesting bit of trivia too is that Monty Python and the Holy Grail also filmed there in the early 1970s.
