Located in the northeast part of Poland, about 30 km northeast of Elblag, Frombork was the former residence of the Polish astronomer, Nicolaus Copernicus. He lived for many years in Frombork and conducted most of his research for his theory here. Copernicus was buried in the Frombork’s cathedral. Frombork’s most interesting part is the Cathedral Hill with its red brick cathedral building surrounded by defensive walls.
The medieval stronghold is dominated by the cathedral, which was built in the 14th century. The Old Bishops’ Palace was built also in the 14th century, which today houses the Copernicus Museum. The castle offers an excellent view over the Vistula Lagoon.
