Focus on this artwork and explain the History.
In the 1970s, Hans Potthof painted the 112-meter concrete wall of the Vorstadtbrücke bridge with the assistance of children; but graffiti destroyed the painting during decades.
In 1995, Cogliatti instructed 55 children to paint the same concrete wall on behalf of the Zuger Schul– und Stadtbauamt (″Zug school and municipal building authorities″). The leitmotiv theme for the painting work was "Living space", the painting was mainly in shades of blue – allusions to the houses that had sunk into the lake there in 1887. The wall painting was inaugurated on July 6, 1995, one day after the complete renovation of the Rigiplatz above, which is reminiscent of the same disaster.After the painting had been repeatedly covered in graffiti, the city commissioned Cogliatti to redesign the wall in 1998. With the help of a flat painter and over a period of approximately 140 hours, the artist implemented “her own sculptural and color visions”. One of Cogliatti's artistic goals, among others, was to use painterly means to give the impression of a third dimension. She therefore gave her work the name Trompe-l'œil, which means "eye delusion"; for this, the dominance of the window hatches in the wall had to be broken. Cogliatti completed the work in early August 1998.
