This historic castle was constructed on three islands and is surrounded by lake and beautiful gardens. Frederiksborg Castle has housed The Museum of National History since 1878. A tour through the museum's many beautiful rooms is an encounter with kings, queens, nobles, the bourgeois, events, and epochs, which have all shaped the country's history and development from the Middle Ages to the 21st century. The museum was founded by brewer J.C. Jacobsen, the founder of Carlsberg.
