Château de Talmont was founded by the Count of Poitou in the 10th century and the first documentary records appear between 1040 and 1046. In 1138 the castle was held by Joscelin de Lezay, who was attacked by Louis VII; despite being considered invulnerable because it could be resupplied from the sea, the castle was burnt by the king. Talmont passed on to the Mauléons by the 1140s, but in 1182 Richard I of England became the lord of Talmont; he remained in control of the castle until his death in 1199, when it was returned to the Mauléon family.
The castle was enlarged during by the King Richard I of England with round towers, curtain wall and new gate. Most of the castle was demolished in the 17th century.
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.
