Frombork's massive 14th-century Gothic Cathedral (1329 - 1388) is the main focal point of the town. A masterpiece of brickwork, the breathtaking interior is packed with Baroque altars and tombstones, and features a gigantic 17th-century Baroque organ, one of the most famous organs in the country. Recitals are often given, and the Cathedral plays host to an annual organ festival during the summer. The key sight now is the grave of Nicolaus Copernicus himself which can be found in the South Nave. Located in the spot where the remains were discovered that were finally proved to be those of Copernicus, the grave features a black granite tombstone which identifies the great man as a canon and the man who discovered the heliocentric theory. The tombstone bears a representation of Copernicus’ model of the solar system – a golden sun encircled by six planets.
