William II, King of the Netherlands and Grand Duke of Luxembourg from 1840 to 1849, governed the Grand Duchy from The Hague. Concerned with strengthening the influence of the House of Orange-Nassau and motivated by economic considerations, he acquired several Luxembourg estates.

In this context, the former Berg Castle and its estate - whose various construction phases remain poorly documented - entered the private property of the King Grand Duke in 1845, following its purchase from Baron Charles Joseph du Pasquier de Dommartin. The sovereign visited the estate the following year.

Transformations under William III and Adolphe
During William III’s reign, extensive works were undertaken under the direction of the royal estate architect Ernest van Koenig, transforming the former Baroque residence into a Neo-Gothic style home.
With the dynastic change, Grand Duke Adolphe became the owner, before his son William IV and his wife Maria Anna of Braganza took up residence after their marriage in 1893.

Reconstruction under William IV
After ascending the throne, William IV initiated an ambitious project to restructure Berg Castle, restoring the old building while adding a more sumptuous modern extension to replace the existing outbuildings. The work was entrusted to the Munich architect Max Ostenrieder (1870–1917), assisted by the Luxembourgish architect Pierre Funck-Eydt (1846–1932).

The original plan intended to preserve the main body of the old Castle, but it proved too dilapidated to save. Ultimately, only the stables, outbuildings, and nineteenth-century entrance tower were retained. Simultaneously, a landscaped park was laid out around the new construction.

Despite the scale of the project - the new castle contained over a hundred rooms - the works were completed in under four years. On 15 September 1911, William IV moved in with his court of around thirty people. Following his death, his daughter, Grand Duchess Marie-Adélaïde, resided there until her abdication in January 1919. Berg Castle was also where her sister, Grand Duchess Charlotte, took her constitutional oath.

Transition to state control and wartime period
In 1934, the Luxembourg State acquired the castle, as well as the furniture for the representative rooms (mainly on the ground floor), leaving them at the disposal of the Grand Ducal Family in accordance with constitutional provisions.

During the Nazi occupation, while the Grand Ducal Family had left Luxembourg, the Castle was requisitioned and converted into a National Socialist school for girls.

Restoration and current residence
The estate has served as the residence of the Head of State and his family.

After the Second World War, the Castle was uninhabitable and extensive restoration and modernisation works were undertaken to return it to residential use. Grand Duchess Charlotte and her family then moved to Fischbach Castle.
Only in 1964, following his swearing-in, did Grand Duke Jean reoccupy Berg Castle. Since then, the estate has served as the residence of the Head of State and his family.
