Karlštějn is the “Castle Royale”, the poster boy of Czech tourism promotion and among the nicest majestic castles Czech Republic has to offer. This castle dates back to 1348 and was founded by no other than Karel IV, the Holy Roman Emperor and King of Bohemia, also inhabited by his son Václav IV. It served as a safe keep where Bohemian crown jewels, imperial regalia, holy relics and other important objects were stored and protected. A 15 minute uphill walk from the parking will take you to the castle and open up a wonderful elevated view of the surrounding areas. If you have more time to spend, take a longer walk (2 hours one way) to Svatý Jan Pod Skalou, you won’t regret it.
