Egeskov was first mentioned in 1405.^[1] The castle structure was erected by Frands Brockenhuus in 1554.^[2] [3]

Due to the troubles caused by the civil war known as the Count's Feud (Danish: Grevens fejde), general civil unrest, and a civil war introducing the Protestant Reformation, most Danish noblemen built their homes as fortifications. The castle is constructed on oakenpiles and located in a small lake with a maximum depth of 5 metres (16 ft). Originally, the only access was by means of a drawbridge. According to legend, it took an entire forest of oak trees to build the foundation, hence the name Egeskov (oak forest).
