The Tour Mélusine is the keep of a former castle in the commune of Vouvant. This keep and watchtower, built at the end of the 12th century or the beginning of the 13th century, is the only vestige of the ancient castle of the Lords of Lusignan built in the present location. This castle was separated from the fortified town of Vouvant by a moat. A chapel, long gone, was leaning against the tower.
This tower, 45 m high from the ditch and with its cylindrical shape, is original from that time. Indeed, the majority of the castles of this region and of this time are of the 'Niortais' style (a square tower with round towers at each corner).
The keep has a square base, which indicates the height of the curtain wall that surrounded the courtyard of the castle, which is today the Place du Bail ('bail' meaning 'fortified enclosure').
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.
