Torun owes its origins to the Teutonic Order, which built a castle
there in the mid-13th century as a base for the conquest and
evangelization of Prussia. It soon developed a commercial role as part
of the Hanseatic League. In the Old and New Town, the many imposing
public and private buildings from the 14th and 15th centuries (among
them the house of Copernicus) are striking evidence of Torun's
importance.
