The birthplace of Copernicus is a picturesque town on the Vistula River and provides some of the best examples of Gothic urban architecture in Central Europe. (And it’s famous for its gingerbread, too.) The tower on the Town Hall dates from 1274 and is the oldest in Poland. The house in which Copernicus was born is now a museum, devoted to his life and work.
