Toledo was walled by Romans, and a lot of its stones were reused later in built walls, as the original perimeter was subsequently tripled. The Visigothic King Wamba renewed the Roman fortifications, sculpting in its gates an inscriptions. The inscriptions were destroyed by the Muslims, and restored in 1575 by the Corregidor Juan Gutiérrez Tello.
The Arabs widened the city and the walls. After the Reconquista, the walls were again advanced in outer line and new gates were constructed. The gates and towers of the Walls of Toledo have survived until these days.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
