The former Crown Prince was officially named King Frederik X of Denmark by Prime Minister Mette Frederiksen from the balcony of Christiansborg Palace in Copenhagen - the home of the Danish Parliament.

While the new King and Queen's main royal residence will continue to be Frederik VIII's Palace at Amalienborg in Copenhagen, the couple and their family do always have the option of returning to their breathtaking summer residence, The Chancellery House at Fredensborg Castle, which also happened to be their first marital home.
Built in 1731, it is a Baroque-style building attached to the main castle via the stable buildings and the church. It used to be the royal couple's primary residence when they first got married in May 2004, until Frederik VIII's Palace at Amalienborg in Copenhagen was renovated.
Not many photos have been shared of the interior, but The Chancellery House is situated on the south side of the newly rebuilt riding ground facility and the exterior features flat, decorative columns.
According to the Kongehuset website, "The Chancellery House’s architecture and interiors are in Baroque style with references to the French régence style." Several of the original features remain today, including stucco ceilings, panelled doors, decorative wrought iron fittings and high wall panels.
Since it was built by architect J.C. Krieger, who was also responsible for the main palace, we've taken a look inside Fredensborg Castle to get an idea of the beautiful interiors.
Known as the Danish yellow lounge, the room follows a bright colour scheme with patterned wallpaper, matching curtains and gold accents, including vintage chairs with gold legs. Wooden floorboards, a red rug, a crystal chandelier and flowers add the finishing touches.
Blue, gold and red are the primary colours decorating the French Library inside Fredensborg Castle. It features a striped sofa and a cream and gold lamp, while an entire wall is taken up by rows of books.
Photographs shared from a dinner party to celebrate King Frederik and Queen Mary of Denmark's engagement hosted in 2003 show the grand dining room inside Fredensborg Castle.
Decorated with plush red carpets that wouldn't be out of place in Hollywood, the hallways appear to be very light, with white walls, tall ceilings and huge windows.
