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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
