Muzeum Pomnika Historii Frombork Zespół Katedralny

The fortified cathedral complex on Frombork's hill dates from the 14th century and is tied to the name of Nicolaus Copernicus. Visitors can step inside the basilica of the Assumption of the Virgin Mary and St Andrew, and the museum tells the story of this religious site. The whole ensemble is a listed national Monument of History, so it pairs well with a walk around the hill.
