Weinsberg castle was established on a mountain at the trade route running from Heilbronn to Schwäbisch Hall around the year 1000. In 1140 the castle was besieged by Konrad III in the course of the struggles between the Staufers and the Welfs. Finally it had to surrender on December 21, 1140, since the army of Welf VI to release the castle had been defeated by the Staufers in a battle. According to the report of the Chronica regia Coloniensis, the women of the castle were granted free departure and allowed to take what they could carry on their backs. They carried down their men, and so saved their lives, since the king adhered to his word. The women became known as treue Weiber ('loyal women'). The castle (today's ruin) is called Weibertreu due to this occurrence.
On April 16, 1525 (Easter Sunday), during the German Peasants' War, the peasants attacked and destroyed the castle, which was already damaged from an earlier attack in 1504. They then proceeded to execute the nobleman who had been in command of both town and castle and who had treated the peasants very badly several times before.
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.
