The architectural ensemble of Amalienborg consists of four mansions located around a square with a monument to the founder of the palace, Frederick V. The Christian VII mansion is used to receive royal guests and hold presentations, while the Christian VIII mansion houses the royal library and the museum of the Danish branch of the Glücksburg dynasty. The Frederick VIII mansion is used as a royal residence, as is the Christian IX mansion, where the now former Queen Margrethe II lives.
