A roughly tonne-heavy water shutoff valve has disappeared from Bergedorf in Hamburg. The cast-iron valve, installed in 1927, was unearthed during pipeline renovation work under Alte Holstenstraße and was meant to be preserved as an exhibit documenting the district's history. It has now vanished without a trace, the Hamburger Abendblatt reports.

For nearly a century the valve did quiet work: it directed water from the Schlossteich along the Bille to the Kornwassermühle, the mill that gives the waterway its name. It was one of those pieces of infrastructure that exists precisely as long as nobody thinks about it — and whose historical value was discovered only when it was dug up for disposal. The plan was to save it, display it, let schoolchildren look at a machine that outlived every government that built it.

Instead, someone with a crane truck, or at least a very strong back and a lot of patience, has taken it. The renovation site is a public street in a residential district; the valve sat there for weeks as an exposed piece of scrap iron in a city where metal theft from public works is a routine cost of doing business. Nothing about a hundred-year-old valve suggests to a passerby that it is worth anything but its weight.

The episode fits a familiar pattern. Institutions are competent at planning exhibitions and poor at protecting the objects for them. The valve had survived a century underground, two world wars' worth of scrap drives, and every municipal reorganisation since Weimar. It survived, in other words, everything except being made someone's responsibility.
