Belfast Rise Sculpture

Rise is a concept £400,000 public art spherical metal sculpture by Wolfgang Buttress. It is 37.5 metres (123 ft) high and 30 metres (98 ft) wide[5] and was constructed in early 2011 in the centre of the Broadway roundabout, at the junction of the Westlink and M1 motorway, a main gateway to the city where (as of 2009) more than 80,000 cars on average flow past it each day. The artwork is made of two geodesic spheres supported on slender stanchions. The engineers, Price & Myers, made extensive use of the work done by Buckminster Fuller in the 1950s. The outer sphere has a geodesic frequency of 8. It required 1920 tubes to be bolted together. Tensigrity – another concept developed by Buckminster Fuller – is used to hold the inner sphere in position.
