The Oude Loo castle was built in the 15th century. In 1684, the castle and the surrounding land was bought by William III of Orange. On this land, he had Het Loo Palace built. The castle was used by the court, among other things as an apothecary. In the 19th century the castle came in the hands of Louis Napoleon who filled up the moat. Queen Wilhelmina of the Netherlands had the castle and the moat restored by architect Pierre Cuypers. Since 1968, the castle is owned by the Dutch state. Since 1973, it is a national heritage site. The castle is currently used by the Dutch Royal Family as a country house and guest residence.
The castle park construction began in the 17th century. Paths, ponds and alternating open spaces and groves of trees have been used to create a varied natural-looking landscape. The western and northern parts were heathland when they were purchased in the 19th century. They were sown to Scots pine and are now varied forest areas interspersed with patches of heath. In this part of the park is an old meltwater valley formed in the most recent ice age, Wilhelmina's Valley. Many of the numerous cultural heritage elements in the park have been restored. Recently, part of the park underwent a makeover to a design by the landscape architect Michael van Gessel.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
