Frederiksborg Palace
Renaissance architecture thrived during the reigns of Frederick II and especially Christian IV. Inspired by the French castles of the times, Flemish architects designed masterpieces such as Kronborg Castle in Helsingør and Frederiksborg Palace in Hillerød. In Copenhagen, Rosenborg Castle (1606–24) and Børsen or the former stock exchange (1640) are perhaps the city's most remarkable Renaissance buildings.
