Karlštejn CastleA must-do excursion
This beautiful fortress was commissioned by Charles IV in the mid 14th century. Gothic in style, with Renaissance features, it sits in a privileged location atop a forested hill. For a long time, it was used to guard the crown jewels. To reach it, you have to go through narrow streets lined with pastel-coloured houses that have been turned into restaurants and souvenir shops. Remember to book in advance.
