On top of the ruins of Bishop Absalon's castle a new building was erected. It was named Copenhagen Castle.
Copenhagen Castle stood for several hundred years and was rebuilt many times in several different styles. The most famous part of Copenhagen Castle was the "Blue Keep", a prison tower where Christian IV’s daughter, Leonora Christina, was imprisoned for 22 years.
During the 1720s, King Frederik IV rebuilt the aging castle thoroughly. Already in 1731, however, his son, King Christian VI, demolished Copenhagen Castle to make way for a new palace: the first Christiansborg Palace.
The ruins of Copenhagen Castle still exist and may be visited in the roofed excavations below the present palace.
