Amalienborg () is the official residence for the Danish royal family, and is located in Copenhagen, Denmark. Queen Margrethe ll resides in the palace during winter and autumn. It 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 monarchs and their families have resided in the four different palaces. History The first palaces on the site The Frederiksstaden district was built on the former grounds of two other palaces. The first palace was called Sophie Amalienborg. It was built by Queen Sophie Amalie, consort to Frederick III, on part of the land which her father-in-law Christian IV had acquired outside of Copenhagen's old walled city, now known as the Indre By district, in the early 17th century when he had been king. Other parts of the land were used for Rosenborg Castle, Nyboder, and the new Eastern fortified wall around the old city.

The presentation was a great success, and it was repeated a few days later on April 19. However, immediately after the start of the second performance a stage decoration caught fire, causing the theatre and the palace to burn to the ground, and about 180 people died. The King planned to rebuild the palace, whose church, Royal Household and garden buildings were still intact. Ole Rømer headed the preparatory work for the rebuilding of Amalienborg in the early 1690s. In 1694, the King negotiated a deal with the Swedish building master Nicodemus Tessin the
