In 2012, Catalan artist Jaume Plensa presented his six-month exhibition EIGHT POETS in public space. Eight illuminated large sculptures set impressive light accents in Bamberg's old town. This was followed by the purchase of the sculpture called “Air-Earth”, which was financed by donations, sponsorship money and foundations. Since then, the Plensa sculpture on the Obere Mühlbrücke has been attracting attention with its shimmering, fascinating glow, especially in the evening hours.
