Corrosion, Gateway Arch

Much ado recently has been made of the corrosion of the Gateway Arch, now coming up on its 50th Anniversary.

I don’t know why I had never noticed it before, but blemishes are clearly visible on the legs of the Arch.

While Modernist structures are often regarded as “new,” it bears reminding that many of these buildings are not new at all anymore, and will require careful conservation in the coming decades.
