Jægerspris Castle on the Hornsherred peninsula west of Copenhagen is one of Denmark's oldest and most beautiful royal residences, with roots dating to the Middle Ages. The three-winged complex features a north wing from the medieval period and was significantly expanded in 1722 with a comprehensive rebuilding by Prince Charles that added extra storeys and symmetrical twin towers. For 600 years it served Danish kings as a hunting and summer residence. In the 1850s, King Frederik VII and his morganatic wife Countess Danner sought refuge here, later transforming it into an asylum for women. Today the museum preserves rooms decorated by Countess Danner in the 1850s style, representing the only complete example of interior design from that era in Denmark.
