Originally known as Årsmarke, it was first mentioned in 1372. Today's building was completed in 1866 to a design by Henrik Steffens Sibbern. The medieval manor of Årsmarke, with its more than 300 years of history, was once Denmark's largest private estate; it is now part of Knuthenborg Safaripark. The exotic shrubs and trees planted during the era of the Counts of Knuthenborg are situated on the grounds.
