The artwork Abendstern (Evening Star ) by Micha Ullman was engraved into a sidewalk slab at the corner of Stauffenberg- and Bolzstraße in 1996. Only attentive passers-by will discover the indentation and perceive it as a work of art, because nothing in the surroundings indicates the artist or the artwork, which both symbolizes a sundial through light and shadow and becomes a mirror of the sky when it rains. It is one of a series of “Minimenten” that Ullman has installed in Stuttgart. Once someone has discovered the Evening Star, it never lets go . Its simplicity leaves room for complex interpretations.
