The Leaning Tower of Toruń is a 14th-century defensive tower that forms part of the city walls, notable for the visible tilt it has developed over the centuries. It leans approximately 1.4 metres out of vertical — less dramatic than Pisa but conspicuous enough that you notice it immediately. The tower is one of nine surviving medieval defensive towers in the city walls.
The lean is the result of ground subsidence in the sandy soil near the Vistula rather than construction error, though local legend attributes it to the penance of a wayward Teutonic Knight. The tower is not open to climb but can be viewed and photographed from the small square below. It sits near the Monastery Gate, one of three surviving medieval city gates.
