Bydgoszcz is a city in northern Poland, straddling the confluence of the Vistula River and its left-bank tributary, the Brda. Bydgoszcz is the eighth-largest city in Poland. It is the seat of Bydgoszcz County and the co-capital, with Toruń, of the Kuyavian-Pomeranian Voivodeship. Bydgoszcz is the seat of Casimir the Great University, University of Technology and Life Sciences and a conservatory, as well as the Medical College of Nicolaus Copernicus University in Toruń. It also hosts the Pomeranian Philharmonic concert hall, the Opera Nova opera house, and Bydgoszcz Airport. Situated between the Vistula and Oder (Odra in Polish) rivers, and by the Bydgoszcz Canal, the city is connected via the Noteć, Warta, Elbe and German canals with the Rhine, a river linked to the Mediterranean and Black Seas by canals and flowing into the North Sea. Bydgoszcz is an architecturally rich city, with gothic, neo-gothic, neo-baroque, neoclassicist, modernist and Art Nouveau styles present, for which it has earned the nickname Little Berlin. The notable granaries on Mill Island and along the riverside belong to one of the most recognized timber-framed landmarks in Poland.
Toruń is a city on the Vistula River in north-central Poland and a UNESCO World Heritage Site. Since 1999, Toruń has been a seat of the local government of the Kuyavian-Pomeranian Voivodeship and is one of its two capitals, together with Bydgoszcz. The cities and neighboring counties form the Bydgoszcz–Toruń twin city metropolitan area. For centuries it was home to people of diverse backgrounds and religions. From 1264 until 1411, Toruń was part of the Hanseatic League and by the 17th century a leading trading point, which greatly affected the city's architecture, ranging from Brick Gothic to Mannerist and Baroque. During the Second World War, Toruń was spared bombing and destruction; its Old Town and iconic central marketplace have been entirely preserved. Toruń is renowned for its Museum of Gingerbread – the gingerbread-baking tradition dates back nearly a millennium – as well as for its large Cathedral. Toruń is noted for its very high standard of living and quality of life. In 1997 the medieval part of the city was designated a UNESCO World Heritage Site. In 2007 the Old Town of Toruń was added to the list of Seven Wonders of Poland. Nicolaus Copernicus, best known as an astronomer - the creator of the heliocentric model of the Solar System and the first heliocentric in Europe was born in Toruń.
