The castle of Kelefa is located about halfway between the current village of Kelefa and the Bay of Oitylo. It was built in 1679 by the Ottomans, in order to contain the Inner Mani region. Some years later, in 1685, the Maniots besieged the castle. They sent messengers to Venice so the Doge could send a fleet to help them capture the castle. The Venetians were currently at war with the Ottomans so they agreed and sent a fleet under Francesco Morosini. As soon the fleets bearing the symbol of St Mark the Ottoman garrison surrendered. A year later the Ottomans returned with a strong force and laid siege to the castle but were driven back. Along with the rest of the Peloponnese, the castle remained in Venetian hands for about 30 years, but in 1715 the Ottomans recaptured the Peloponnese. Around 1780 the Ottomans abandoned the castle, which became derelict.
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.
