The Castle of Zakynthos was completed by the Venetians in 1646 AD and the Winged Lion of Saint Mark, a symbol of the Venetian empire, stands above the main entrance. In those times the castle was the seat and residence of the Venetian Proveditor, administrator of the island, and other officials. Due to time, war attacks and earthquakes, the castle was partly damaged.
When the British Empire took over the Ionian islands in 1812, the castle was reconstructed and new buildings were built, including barracks, powder stores and the house of the British Parliament.
Many churches were also found inside the castle walls, such as the Byzantine Church of the Savior (San Salvatore or Domo) that dates from the 12th century, the 14th century Church of Saint Francis, the church of Santa Barbara, the church of the Virgin Mary Laurentena and the church of Saint John the Baptist.
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.
