Here the Poltwa disappears underground |
The Poltwa ( Ukrainian Полтва , Polish Pełtew , German rarely Polten or Pelten ) is a river in western Ukraine that crosses the city of Lviv underground.
Since Lviv is on the European watershed , all major rivers are far from the city.
The source of the 70 km long river is located in Lviv Pohulyanka Park, about 350 meters above sea level. In the Middle Ages, the river bed formed part of the moat along the city wall. The river flows further through the Roztocze range of hills and flows into the Bug River on the left, near the city of Busk at an altitude of 220 m above sea level. After leaving the Lviv city area, the Poltwa flows openly and receives some tributaries.
The Poltwa formed an island on today's Mickiewicz Square, on which there was a statue of the Virgin Mary. The open river bed, which carried sewage from the adjoining properties, posed a risk of epidemics for the residents, therefore, according to the decision of the city council at the end of the 19th century, it was enclosed in walls, vaulted and filled in, while the river bed was straightened in some sections. This created the main sewer of the urban mixed system . In addition to the underground course of the river, the building of the Lviv National Opera was built in the former marshland by the architect Zygmunt Gorgolewski from 1897 to 1900 . In the basement of the theater, the rushing of the river can still be heard.
