The Guaita fortress is the oldest of the three towers constructed on Monte Titano, and the most famous. It was built in the 11th century and served briefly as a prison. It is one of the three towers depicted on both the national flag and coat of arms. It was registered as one of the World Heritage Sites in 2008.
Guaita was rebuilt in the second half of the 15th century and in the 16th century has been covered with a sloping roof. It is called the Rocca Guaita and, within its solid walls, protected by double walls (the external wall with merlons and truncated towers at the corners), the population found refuge during sieges.
The upper entrance door, which can be reached by a staircase, is protected by a small wooden construction of 1481. The courtyard contains some pieces of artillery from the Second World War: two mortars, a gift from Vittorio Emanuele II, two 75mm canons fired by the Guardians of the Rocca during national festivities, a gift of Vittorio Emanuele III.
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.
