Toruń is an ancient city in northern Poland, on the Vistula River. Toruń is one of the oldest cities in Poland. The medieval old town of Toruń is the birthplace of the astronomer Nicolaus Copernicus.
In 1997 the medieval part of the city was designated a UNESCO World Heritage Site. In 2007 the Old Town in Toruń was added to the list of Seven Wonders of Poland. National Geographic Polska rated the old town market and the Gothic town hall as one of the "30 Most Beautiful Places in the World". Since 1999, Toruń has been a seat of the self-government of the Kujawy-Pomerania Province and, as such, is one of its two capitals (together with Bydgoszcz). The cities and neighboring counties form the Bydgoszcz-Toruń bi-polar metropolitan area. In September 2004, Bydgoszcz Medical School joined Toruń's Nicolaus Copernicus University as its Collegium Medicum.
