Grand Hotel in Sopot, Poland was originally built in 1924–1927 at a cost of 20 million Danzig gulden as the most refined hotel in Sopot - the Kasino Hotel. As the Sofitel Grand Hotel, it is located at the seaside of the Gdansk Bay, in the heart of the town and next to the beach. Sofitel Grand Hotel has been totally refurbished during the last years, the classical atmosphere from the earlier period is still present and the hotel is now both classical, and modern. In 2007 it was decided to open Grand Spa by Algotherm, this to maintain the history of Sopot as a Spa resort.
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.
