Younger, who spent some time in Copenhagen that summer reviewing the property. His drawing and model were completed in 1697. The King, however, found the plans too ambitious and instead began tearing down the existing buildings that same year, with the reclaimed building materials used to build a new Garrison Church. The second Amalienborg was built by Frederick IV at the beginning of his reign. The second Amalienborg consisted of a summerhouse, a central pavilion with orangeries, and arcades on both side of the pavilion. On one side of the buildings was a French-style garden, and on the other side were military drill grounds. The pavilion had a dining room on the groundfloor. On the upper floor was a salon with a view out to the harbour, the garden and the drill grounds. Development of Frederiksstaden by Frederick V Amalienborg is the centrepiece of Frederiksstaden, a district that was launched by King Frederick V to commemorate in 1748 the tercentenary of the Oldenburg family's ascent to the throne of Denmark, and in 1749 the tercentenary of the coronation of Christian I of Denmark.

These mansions (now called Palaces) form the modern palace of Amalienborg, albeit much modified over the years. As a royal residence When the Royal Family found themselves homeless after the Christiansborg Palace fire of 1794, the palaces were empty for long periods throughout the year, with the exception of the Brockdorff Palace, which housed the Naval Academy. The noblemen who owned them were willing to part with their mansions for promotion and money, and the Moltke and Schack Palaces were acquired in the course of a few days. Since that date successive royal family members have lived at Amalienborg as a royal residence and kings have lent their names to the four palaces; Christian VII's Palace, Christian VIII's Palace, Frederick VIII's Palace and Christian IX's Palace. A colonnade, designed by royal architect Caspar Frederik Harsdorff, was added in 1794–1795 to connect the
