by Frederick II and becoming the largest Renaissance residence in Scandinavia. Situated on three islets in the Slotssøen (castle lake), it is adjoined by a large formal garden in the Baroque style.
After a serious fire in 1859, the castle was rebuilt on the basis of old plans and paintings. Thanks to public support and the brewer J. C. Jacobsen, the building and its apartments were fully restored by 1882 when it was reopened to the public as the Danish Museum of National History. Open throughout the year, the museum contains the largest collection of portrait paintings in Denmark. It also provides visitors with an opportunity to visit several of the castle's state rooms including the restored Valdemar Room and Great Hall as well as the Chapel and the Audience Chamber which were both largely spared by the fire and contain sumptuous decorations.
