When the royals are not using the palace, it is possible to visit as a regular guest. The palace consists of five places to visit: The Royal Reception Rooms with The Great Hall and the Queen's Tapestries, The Royal Stables, The Royal Kitchen, the Ruins under Christiansborg and Christiansborg Chapel.
Right next to the castle is Christian IV's Brewery, which you can also experience as a guest.
