Rosersberg Palace - A royal residence on the shores of Lake Mälaren

Rosersberg Palace, located on the shores of Lake Mälaren near Stockholm, was built in the 1630s by the Oxenstierna family. Gabriel Bengtsson Oxenstierna named the palace after his mother, who came from the Tre Rosor family. Construction in the Renaissance style began in 1634 and was completed in 1638.

By the late 17th century, the Renaissance style was out of fashion. Oxenstierna's son, Bengt Oxenstierna, had the building radically modernised in the Baroque style under the architect Nicodemus Tessin the Younger. During this time, the gables of the main building were demolished, a new roof was added, and new wings and a colonnaded gallery were constructed.

In 1747, the palace was acquired by Baron Erland Carlsson Broman, who modernised it with the assistance of architect Jean Eric Rehn. After Broman died in 1757, the state acquired the palace and gave it to Duke Charles, the younger brother of Gustav III. Charles took up residence there and continued Rehn's plans, renovating the interior in the late Gustavian style. This style featured a serious and romantic tone known as the Charles XIII Empire style, resulting in interiors such as the Orange and Red drawing rooms and the Hogland Room.

The palace was a favourite for Charles XIV John and Queen Desideria, the first of the Bernadotte line, who spent their summers at Rosersberg. They were the last royals to use the palace as a residence. Today, the rooms and collections are preserved as they were during the period 1795–1825, with Charles John's bedchamber regarded as an important example of early 19th-century Swedish interior design.

After Desideria died in 1860, the palace was given to the Swedish infantry. The Swedish Infantry Gunnery School moved into the ground floor and wings in 1874 before relocating in 1961. The castle was then handed over to the Swedish Civil Defence Board, and later to the Rescue Services Agency. In the summer of 2008, Rosersberg Hotel and Conference opened a café and bed and breakfast on the grounds.
