Frederiksborg Castle (Danish: Slot Frederiksborg) is a moated castle in Hillerød on the Danish island of Zealand. It is considered the largest and most significant building of the Nordic Renaissance and today houses the Danish National –History Museum. The present-day castle was built under Christian IV. He is regarded as one of the most enthusiastic builders of his time in Northern Europe: Revenue from the Sound Toll provided him with extensive financial resources, which made possible, among other things, the construction of the palaces at Glückstadt, Rosenborg, and Halmstad. The king had his largest palace built in Hillerød. He had the old hunting lodge there demolished and commissioned architect Hans van Steenwinkel to build the new palace, named after his father, on three small islands in Lake Frederiksborg.
