ORP Błyskawica is a Grom-class destroyer which served in the Polish Navy during World War II and is the only ship of the Polish Navy awarded the Virtuti Militari medal. It is preserved as a museum ship in Gdynia, the oldest preserved destroyer in the world. It was the second of two Grom-class destroyers, built for the Polish Navy by J. Samuel White, Cowes in 1935–37. The name means Lightning. The two Groms were some of the most heavily-armed and fastest destroyers on the seas before World War II.
Two days before the war, on 30 August 1939, the Błyskawica withdrew, along with the destroyers Grom and Burza, from the Baltic Sea to Britain in accordance with the Peking Plan to avoid open conflict with Germany and possible destruction. From then on they acted in tandem with the Royal Navy's Home Fleet.
During the World War II Błyskawica took part in convoy and patrol duties in Norwegian Coast, Atlantic and Mediterranean. On 7 September 1939, Błyskawica made contact with and attacked a U-Boat, possibly the first combat between the Allied and the German fleets.
After the war, the ship returned to Poland. Since 1 May 1976, it has served as a museum ship in Gdynia.
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.
