Hrad Křivoklát, Křivoklát, Czech Republic
For travelers looking for a castle tour that feels like taking a trip back in time, it’s hard to beat a trip to Krivoklat Castle in the Berounka River Valley. Perched atop a forested hill, the castle was built as a royal residence in the 13th century. Its secluded location has helped to preserve the castle’s Gothic interiors, which are filled with paintings, art and more than 50,000 volumes of books. Used to house political prisoners during the Middle Ages, the castle features some unusual reminders of its darker past, including carvings in the Royal Chapel that depict angels bearing instruments of torture.
