Fort Lupin, also known as Fort de la Charente, is an artillery battery in Saint-Nazaire-sur-Charente, in the department of Charente-Maritime. It was built in the 1680s to a design by Sébastien Le Prestre de Vauban, and it is now in good condition.
The fort consists of a semi-circular gun battery ringed by a parapet with twenty-two embrasures. A tour-réduit and two blockhouses are located at the gorge. The fort is further protected by a ditch, a covertway and a glacis.
Fort Lupin was never attacked, and it never fired its guns in anger. It was decommissioned in the late 19th century, and was subsequently abandoned and vandalized.
The fort was sold to a private owner in 1964. The owners have restored the fort, and today it is in good condition. It is not open to the public on a regular basis.
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.
