Skjoldenæsholm Castle was originally located 1.5 km to the south of the current house. Skjoldenæs is first recorded in the 1340s when it was owned by the crown and referred to as a 'castle of considerable size'. King Christopher II mortaged the estate to John III, Count of Holstein-Plön. King Valdemar IV can with certainty be linked to the locale, in either 1346 or 1348, when he besieged the castle.
The medieval castle was demolished in 1567 but a castle bank surrounded by moats can still be seen at the site today. The estate was crown land for an extended period of time, held in fee by various members of the Danish nobility until 1662 when it was ceded to the King's rentemester Henrik Müller. Over the next few years, between 1663 and 1666, Müller completed a new manor house, half-timbered and in one storey, at the site of the current main building.
After Müller's death in 1682, the estate was reacquired by the king, Christian V, who the following year gave it to his half-brother Ulrik Frederik Gyldenløve, who also owned the Gyldenløve Mansion in Copenhagen as well as several other estates in Denmark and in Norway. After his death, Skjoldenæsjolm remained in his family for almost a century. Count Ferdinand Anton Danneskiold-Laurvig, Ulrik Frederik Gyldenløve's son, owned the property from 1720 until his death in 1754. Anna Joachimine Danneskiold-Laurvig, the widow after his son, replaced the old main wing with the one seen today in 1766.
Anna Joachimine Danneskiold-Laurvig was the last member of the family to own Skjoldenæsholm, selling the property in 1794, shortly before her death the following year. The buyer was Anna Marie Bruun de Neergaard (née Møller) and Skjoldenæsholm has remained in the Bruun de Neergaard's ownership. The main building was in 1971 converted into a conference centre. Today estate covers 1,272 hectares of land, including Skjoldenæsholm Tramway Museum which was founded in 1978 and a golf course. The rest consists mainly of forest.
The sober Neoclassical main wing from 1766 stands in washed, yellow brick. The architect is not known but may have been Philip de Lange. Originally, the red hip roof also covered the three-bay median risalits, found on both sides of the main wing, which received their triangular pediment in connection with a major renovation in 1703. The renovation also added a new east wing and gave the old half-timbered west wing a new facade in masonry towards the courtyard, which matched it. The interior displays several fine examples of 18th-century period decorations.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
