Some ruins are a single building you can hold in your head. This isn’t one of them. The paper mill at Cairate is less a building than a small town gone to seed — sheds and halls and silos strung out along the floor of the valley, a canal still running through the middle of it, roofs caving in at their own pace, the forest coming up the slopes and over the walls to meet itself in the centre. It’s huge. You could spend a day in there and not open every door, and that’s exactly what makes it so good to explore.

You get your first sense of the scale from above, from a broken roofline: red tiles running off in every direction, the tall brick chimney still standing watch over all of it, the green of the valley pressing in hard on every side. Paper was made here for the better part of a century — pulp, water drawn off the canal, steam, the constant noise of it — and now the loudest thing is the wind moving through the empty window frames.

The two round towers are what I’d come for. They stand at one end like the drums of some half-finished fortress, concrete streaked and tagged, ivy climbing the ochre walls at their base. From below they’re almost beautiful, in the way these huge useless shapes get beautiful once nobody needs them anymore.

It’s not a building, it’s a small town — sheds, silos, a canal running through the middle. You could explore for a day and not open every door.

Inside, you learn to watch your feet. Whole floors have come down in slabs, concrete folded like cardboard, rebar bent into the shape of whatever it landed on. Ferns grow where the machines stood. Light falls through the holes in the roof in hard bars, picking out the dust, and everywhere there’s that smell of wet plaster and rust and green things growing in the dark.

The slow undoing

What gets me about a place like this is the arithmetic of it. A hundred years and the work of thousands of people went into building and running it — and it’ll take the valley a fraction of that to take the whole thing back. Concrete that was poured to last forever is already going soft at the edges. The roofs that kept the rain off for generations now let it in on purpose, and the rain is patient, and the trees are patient, and neither of them is in any hurry.

I spent a long morning in there and never saw the same kind of decay twice — every hall had found its own way of falling down. By the time I climbed back out to the chimney and looked over the red roofs one more time, the place had stopped feeling abandoned and started feeling like it was simply busy with something else now: the long, quiet work of becoming a hillside again.
