Pieštvė

Pieštvė (also known as Beisten, Bisten, Pistene, Pista, Pestwa, etc. in medieval chronicles) was a wooden fortress of the Grand Duchy of Lithuania during the Lithuanian Crusade. It stood on a hill fort that is known as Palemon Hill in Seredžius, Jurbarkas District Municipality, Lithuania, located near the confluence of the Neman and Dubysa rivers. It was an important Lithuanian defensive outpost against the Teutonic Order. It was first mentioned in written sources in 1293 and attacked numerous times by the Order. Because it stood near Junigeda (Veliuona), both fortresses were often attacked together. It was burned down in 1363, a year following the fall of Kaunas Castle. It was rebuilt in May 1412 but lost its strategic importance after the Treaty of Melno (1422) and was abandoned. Earlier historians thought that Pieštvė was identical to Bisena.
