kunstwegen-Objekt "Denkmal für Normalnull (II)"

Timm Ulrichs, "Denkmal für Normalnull (II)", 1969/28.11.80 Exactly 22.12 m below the central marker cross of this granite slab is a small water cylinder two-thirds full, the surface of which corresponds exactly to the globally binding Amsterdam zero level: a "beDENKe-Mal" by Timm Ulrichs for the many (invisible) agreements that determine our image of reality and yet could just as easily have been defined quite differently.
