Viaduct over Bober

The viaduct in Bolesławiec is not only one of the longest constructions of that type in Poland but also in Europe. It was built from stone and is composed of 35 arched spans. It has 490 m in length and 26 m in width. Its architecture arrangement draws inspiration from Roman aqueducts.

After the installation of illumination in 2006, the construction presents itself best at night. The construction's project started in 1846 and was ceremoniously opened by Frederick William IV of Prussia himself. The viaduct was of great importance for the region because it provided a rail connection from Bolesławiec to Wrocław and Drezno. In 1945, retreating Germans blew up the west span situated directly over the river of Bober.

The span was rebuilt in 1947 resuming the traffic between the aforementioned cities. The next renovation was carried out from 1984 to 1985 due to the electrification of the railway line. Nowadays, the viaduct is one of the most characteristic objects in the city and is sometimes considered one of the most interesting monuments of technics in this part of Europe.
