Charlottenlund Palace () is a former royal summer residence in Charlottenlund, some north of central Copenhagen, Denmark. The palace was named after Princess Charlotte Amalie, who was responsible for the construction of the original palace. It was later extended and adapted for Crown Prince Frederick VIII to a design by Ferdinand Meldahl in the early 1880s. From 1935 to 2017, the building has housed the Danish Biological Station (Dansk Biologisk Station), later renamed Danish Fishery Survey and in the final years called DTU Aqua. It is now a cultural event venue. The Great Hall is occasionally used for classical concerts. History Origins In 1622, King Christian IV established a new deer park at the site, which was to replace Rosenborg Deer Park at Rosenborg Castle just outside Copenhagen. It was referred to variously as "Kongens nye dyrehave ved Skovshoved" ("The King's new deer park at Skovshoved"), "Gentofte dyrehave ved stranden" ("Gentofte deer park by the beach"), "Den lille dyrehave ved Ibstrub" ("The small deer park at Ibstrub") and "Freudendahl". In 1663, King Frederick III ceded the deer park to one of his courtiers, Jacob Petersen (kammertjener, later rigsbaron). With Henrik Ruse, he opened an inn at the site. Gyldenlund Due to a dispute at the court, Jacob Petersen had to leave the country. After his property was then taken over by Ulrik Frederik Gyldenløve, an acknowledged illegitimate son of King Frederick III, it became known as Gyldenlund after its new owner. He renovated the buildings as well as the fishing ponds and constructed a new summer residence in the grounds. The exact location of the new house is not known but it is assumed that it was located at the site of the current palace. Gyldenløve had owned Gyldenlund for some ten years when Frederick III claimed it back in exchange for Skjoldenæsholm at Ringsted. The king used the house as a summer retreat and for hunting. Christian V constructed Jægersborg Allé in 1706, originally as a private road, connecting the two royal residences in Charlottenlund and Jægersborg. Charlottenlund In 1730, Crown Prince Christian (VI) gave Gyldenlund to his sister, Princess Charlotte Amalie. She replaced the house with a new building in the Baroque style. The construction took place under supervision of Engineer Officer H. H. Scheel, probably to a design by Johan Cornelius Krieger. Many of the building materials came from Copenhagen Castle which was under demolition. In the
