Poltva
River in Ukraine
The Poltva (Ukrainian: Полтва; Polish: Pełtew) is a river in the western Ukrainian Oblast of Lviv and a tributary of the Bug. The Poltva valley cuts between the Podilian Plateau and Roztichia.[1] The capital of the Lviv Oblast, Lviv, is located on the river, with the river flowing directly beneath Lviv's central street, Liberty Avenue , and the Lviv Theatre of Opera and Ballet.[2]
The river once faced significant problems with pollution.[3] As a result, the river was covered up and included into the underground sewer system of Lviv, beginning in 1839.[4] During World War 2, Jews fleeing Nazi violence used the underground river as a hiding place.[5]
