Torun is a city in northern Poland, on the Vistula River, with population over 207,190 as of 2006, making it the second largest city of the Kujawy-Pomerania Province, after Bydgoszcz. The medieval old town of Toruń is a birthplace of Nicolaus Copernicus. It was inscribed onto the World Heritage List of UNESCO as World Heritage Site in 1997.
Previously it was a capital of Toruń Voivodeship (1975-98) and Pomeranian Voivodeship (1921-45). Since 1999 Toruń has been a seat of the self-government of Kujawy-Pomerania Province and, as such, one of its two capitals (together with Bydgoszcz). The cities and neighbouring poviats form the Bydgoszcz-Toruń bipolar metropolitan area. In September 2004, Bydgoszcz Medical School joined Toruń's Nicolaus Copernicus University as its Collegium Medicum.
