This was part of Wałcz becoming a modern city.
The municipal waterworks and tower entered service in 1902. For decades the structure did the unromantic work that makes urban life possible: storing and distributing drinking water at pressure. It continued in use into the late 20th century before being taken out of service in 1999.
By then the tower had already changed physically. The original upper brickwork was altered during its working life, and later redevelopment paired the surviving tower with new apartment architecture. That history is messy in the best way: this is not a museum frozen at one date. It is infrastructure that kept being adapted because the city around it kept changing.
The conversion kept the cylinder in charge.
The largest apartment occupies three levels and reaches into the historic tower, with round brick walls and a spiral staircase making the old geometry unavoidable. You do not enter a square apartment that happens to touch a landmark. The tower organizes the space.
Living vertically is not branding here.
Bedrooms, bathrooms and living areas are distributed across levels. The spiral stair is ordinary circulation now, but it still tells the truth about the building: height was once the engineering solution, and height remains the defining experience.
