Horsholm is a rich city on the Oresund coast approximately 25 km 15.53 mi north of Copenhagen, Denmark. It covers most of Hørsholm Municipality and straddles the borders neighbouring Fredensborg Municipality and Rudersdal Municipality. Horsholm proper is developed around Hirschholm Palace which were constructed in the 1730s but the town has later absorbed several of the nearby communities that are of much older origins. Hørsholm was founded in connection with the construction of Hirschholm Palace. Niels Eigtved created a plan for a residence town in 1737 and to stimulate its growth, it was given status as market town in 1739. However, it never came to serve as a market town and was still only a small settlement when the palace was demolished between 1810 and 1816.
Over the following decades it grew as a garrison town and a local centre for trade. Trommen "The Drum" is Hørsholm's principal cultural centre and also home to its main library. Hørsholm is home to several museums. Rungstedlund is the former home of the author Karen Blixen and is now home to the Karen Blixen Museum.
