Tvangeste is a Russian/Canadian symphonic black metal duo composed of husband and wife Mikhail "Miron" Chirva and Naturelle Chirva.
The band's name comes from Twangste (also spelled as Tuwangste, Tvankste or Twankste), an Old Prussian word meaning "Dam". Twangste was also the name of a small Old Prussian village roughly located at what is now the city of Kaliningrad (known as Königsberg until 1946) that was seized in 1255 by the Teutonic Knights. In the site of the settlement, the now-demolished Königsberg Castle was built. (The House of Soviets now stands on the former site of the castle.)
