Nicolaus Copernicus, one of the world’s most famous astronomers whose books brought about a revolution in Renaissance science, was born in Torun but carried out the majority of his research in Frombork. From 1513 he was a canon of the Warmian Bishopric and used one of the towers in Frombork as an observatory, and it was there that he worked on his notorious De revolutionibus orbium coelestium. Nowadays visitors to Frombork can head to the museum in the Old Bishops’ Palace, which houses many exhibits connected with the life and work of this scholar, including manuscripts and early editions of his books. There is also a copy of Jan Matejko’s painting Astronomer Copernicus. Dialogue with God.

Apart from the interesting exhibition, the remainder of the imposing Cathedral Hill is undoubtedly worth exploration. This monumental cathedral is a redbrick Gothic construction decorated with many turrets. Inside you can view the interesting Baroque organ, or even hear it being played if you visit at one of the Sunday summer recitals organised during International Festival of Organ Music, as well as discover the intriguing tombstones and epitaphs elsewhere in the edifice. Another place to visit is the belfry and its planetarium, and if you still doubt that the Earth rotates, take a look at the Foucault pendulum in one of the towers.

Apart from being a tourist destination, Frombork serves as a fishing and sailing port due to its location on the bank of the Vistula Lagoon. From the local port you can go for a cruise on the Lagoon or have a trip on a ship or hydrofoil to Krynica Morska, Elblag or even Kaliningrad in Russia. If you want to enjoy water sports, such as sailing, you can acquire experience on the challenging conditions of the Lagoon. Sailing its waters resembles to some extent lake sailing, and yet is also similar to a real sea adventure. If you come in the winter, then ski sailing is popular.
