The Royal Palace Oslo (Norwegian: Det kongelige slott) is the official residence of the Norwegian monarch located in the center of Oslo, the capital city of Norway. The palace was built in the 19th century and completed in 1849. It was designed by the Norwegian architect, Hans Linstow, who also designed other important public buildings in Norway.

The palace has a classicist style and is made of yellow brick with white columns and balustrades. It has 173 rooms, including a banquet hall, a ballroom, and a library. The interior of the palace is richly decorated with works of art, antique furniture, and tapestries. The palace also has extensive gardens that are open to the public during the summer months.

The Royal Palace is the venue for important national events and ceremonies, such as the New Year's Eve fireworks display and the Royal Family's public appearances on the balcony on Norway's National Day. Visitors can take guided tours of the palace during the summer months to see some of the palace's impressive rooms and learn about its history and its role in the Norwegian monarchy.
