The Red Tower (which is actually white) is the only defence tower left from medieval Hanseatic city of New-Pärnu. It is the oldest city’s architectural monument and was used as the prison. According to the chronics, in 14th century Pärnu was encircled by a fortified wall with many towers: the round Viliand Tower, also know as the White Tower, in the north-eastern corner and Red Tower in the south-eastern corner. There may have been also the Holy Spirit’s Tower. After a well-needed reconstruction in 1893 it acquired its current look.
The tower got it's name by the red lining covering both its inside and outside. In 1624, the tower had four floors and a six meter deep prison floor. Three floors been preserved. Red Tower was restored in 1973-1980 without it's original brick lining.

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.
