In 1970, the kinetic sculptor Rowland Emett was commissioned to design and build a "water-powered" clock known as "The Aqua Horological Tintinnabulator". The clock was installed in late 1972 and chimed on the hour and half-hour, playing "Gigue en Rondeau II" (1724) from Rameau's "Pieces de Clavecin" Suite in E minor. This musical animated sculpture was originally located on the lower mall and was a popular meeting place. The clock was later modified to chime and play the music every fifteen minutes. In February 2014 the clock was dismantled and refurbished by engineer Pete Dexter and the Rowland Emett Society. It was reassembled for exhibition in Millennium Point, Birmingham, during the summer of 2014 before being dismantled again and stored until December 2014. The parts were then transported back to Nottingham, where Dexter and Intu Victoria Centre staff carried out further refurbishment work. It was reassembled in its new location, at the north end of the upper mall. Its stature, colour scheme, and most of its original water features were restored. It was officially restarted on 17 June 2015.
