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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
