The Jewish Cemetery in Worms is usually called the oldest surviving Jewish cemetery in Europe. The Jewish community of Worms was established by the early eleventh century, and the oldest tombstone still legible dates from 1058/59. The cemetery was closed in 1911, when a new cemetery was inaugurated. Some family burials continued until the late 1930s. The older part contains still about 1300 tombstones, the newer part (on the wall of the former city fortifications, acquired after 1689, more than 1200.
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.
