The clock forms a bridge between two parts of the Anker Insurance Company's building. The clock itself is adorned with mosaic ornaments. In the course of 12 hours, twelve historical figures or pairs of figures move across the bridge among them Joseph Haydn, medieval lyricist Walther von der Vogelweide, Empress Maria Theresa and Prince Eugen of Savoya. Every day at noon, all figures parade accompanied by music from the various eras. This tourist spectacle is a special kind of Viennese High Noon.

'Ankeruhr' aims to commemorate Vienna's past and the transitory state of live and being.
