Het Oude Loo

Het Oude Loo is a historic 15th-century castle located in Apeldoorn, within the province of Gelderland in the Netherlands. Situated on the expansive estate of Het Loo Palace at Koninklijk Park 17, the structure was originally constructed as a hunting lodge, known in German tradition as a Jagdschloss. Although specific details regarding its architectural style are not explicitly defined in available records, the castle is traditionally characterized by its surrounding moat, a defensive feature that has been altered over the centuries. The site holds the official designation of a Rijksmonument, recognizing it as a protected national heritage site of significant cultural value.

The property possesses a rich history intertwined with European royalty. In 1684, William III of Orange purchased the castle and the adjacent land, subsequently commissioning the construction of the grand Het Loo Palace nearby. During this era, the older castle served various functional roles for the court, including use as an apothecary. The landscape changed notably in the early 19th century when Louis Napoleon ordered the moat to be filled in. Following the restoration of the House of Orange-Nassau in 1813, King William I took ownership of the estate, ensuring its continued status as a royal possession through subsequent generations.

Today, Het Oude Loo remains an active part of the Dutch royal family's portfolio, functioning as a private country house and guest residence. Unlike many historical castles that serve as public museums, this building is not open to visitors, maintaining an air of exclusivity and privacy. Its enduring presence on the grounds of the larger palace complex highlights its long-standing importance as a subsidiary residence for monarchs and dignitaries. The castle stands as a quiet testament to centuries of royal history, preserved largely for official use rather than public tourism.
