recently occupied King's palace, Moltke Palace, with that of the Crown Prince, Schack's Palace. The four palaces According to Eigtved's master plans for Frederikstad and the Amalienborg Palaces, the four palaces surrounding the plaza were conceived of as town mansions for the families of chosen nobility. Their exteriors were identical, but interiors differed. The site on which the aristocrats could build was given to them free of charge, and they were further exempted from taxes and duties. The only conditions were that the palaces should comply exactly to the Frederikstad architectural specifications, and that they should be built within a specified time framework. Building of the palaces on the western side of the square started in 1750. When Eigtved died in 1754 the two western palaces had been completed. The work on the other palaces was continued by Eigtved's colleague and rival, Lauritz de Thurah strictly according to Eigtved's plans. The palaces were completed in 1760. The four palaces are: Christian VII's Palace, originally known as Moltke's Palace Christian VIII's Palace, originally known as Levetzau's Palace Frederick VIII's Palace, originally known as Brockdorff's Palace Christian IX's Palace, originally known as Schack's Palace Currently, only the palaces of Christian VII and Christian VIII are open to the public. Christian VII's Palace Christian VII's Palace is also known as Moltke's Palace, and was originally built for Lord High Steward Adam Gottlob Moltke. It is the southwestern palace, and has been since 1885 used to accommodate and entertain prominent guests, for receptions, and for ceremonial purposes. Moltke's Palace was erected in 1750–54 by the best craftsmen and artists of their day under the supervision of Eigtved. It was the most expensive of the four palaces at the time it was built, and had the most extravagant interiors. Its Great Hall (Riddersalen) featured woodcarvings (boiserie) by Louis August le Clerc, paintings by François Boucher and stucco by Giovanni Battista Fossati, and is acknowledged widely as perhaps the finest Danish Rococo interior. The mansion formally opened on 30 March 1754, the King's thirtieth birthday. Due to Eigtved's death a few months later, final work such as the Banqueting Hall, was completed by Nicolas-Henri Jardin. Immediately after the Christiansborg Palace fire in February 1794 and two years after the death of the original owner, the royal family, headed by the King Christian VII, purchased the first of the four palaces to be sold to the royal
