Bothwell Castle is a large medieval castle, sited on a high, steep bank, above a bend in the River Clyde. Construction of the castle was begun in the 13th century by the ancestors of Clan Murray, to guard a strategic crossing point of the Clyde. Bothwell played a key role in Scotland's Wars of Independence, changing hands several times.
The huge cylindrical donjon was built in the 13th century, but before the rest of the castle was completed it was severely damaged in a series of sieges. Rebuilding in the early 15th century enlarged the castle, but it was abandoned by the 18th century. The present ruin is rectangular, with the remains of the donjon to the west, and the later Great Hall to the east. The courtyard is enclosed by long curtain walls, with round towers at the south-east and south-west corners.
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.
