Schloss Oranienstein

About

Schloss Oranienstein is one of the palaces of the House of Orange-Nassau, sited at Diez on the Lahn. It was built on the ruins of Dierstein Abbey between 1672 and 1681 for Countess Albertine Agnes of Nassau after she was widowed. After the French Republican invasion destroyed the Dutch Republic in 1795, stadtholder William V, Prince of Orange and his family first fled to England, before settling in Oranienstein for several years.

Here, William and his son William Frederick issued the Oranienstein Letters, recognising the Batavian Republic and renouncing their stadtholderate and territorial claims in the Netherlands in return for financial and territorial compensation elsewhere, granted by First Consul Napoleon Bonaparte. In 1806, the castle fell to the newly formed Grand Duchy of Berg. Napoleon auctioned off the castle's entire contents in 1811.

After Napoleon's defeat, the Congress of Vienna assigned Oranienstein to the Duchy of Nassau. Following Nassau's defeat of the in the Austro-Prussian War, the Duchy was annexed by Prussia in 1866. One year later, the palace was turned over to the Royal Prussian Army, which established a cadet school in Oranienstein.
