In the northwest corner of the cathedral grounds is Copernicus' tower, and in the southwest corner an octagonal building with a square bell tower and a small planetarium and a Foucault's pendulum. From atop the tower one can survey the town, the tiny harbor, the panorama of the Baltic Sea, and much of Warmia's countryside.
