According to Wikipedia: "Amalienborg... consists of four identical classical palace façades with rococo interiors around an octagonal courtyard; in the centre of the square is a monumental equestrian statue of Amalienborg's founder, King Frederick V. Amalienborg was originally built for four noble families; however, when Christiansborg Palace burned on 26 February 1794, the royal family bought the palaces and moved in. Over the years various kings and their families have resided in the four different palaces."
