De La Fratta or Cesta is one of three peaks which overlook the city of San Marino. The other two are Guaita and Montale. The tower is located on the highest of Monte Titano's summits. A museum to honor Saint Marinus, created in 1956, is located in this tower and showcases over 1,550 weapons dating from the medieval era to the modern day. It was constructed in the 13th century on the remains of an older Roman fort. Just like other two towers in San Marino, it is also depicted on the national flag.
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.
