Union Square Colonnade Consists Of Four Different light sculptures ranging in height from 18 to 24 feet. Each sculpture is an individual work that also functions visually as part of a linear ensemble bordering the newly redesigned square. R.M. Fischer’s design approach combines references to San Francisco’s famous Victorian architecture with natural and modern forms. Developing the sculptures as the world focused on the new millennium, Fischer wanted the forms to appear futuristic and historic simultaneously. Three of the sculptures combine cast aluminum historic street lamp components juxtaposed with contemporary polished steel globes and large, clear illuminated polycarbonate spheres. The fourth reflects a more modernist aesthetic with a single, large stainless steel sphere, horizontally split and lit from within. All four works are mounted on 13-foot tall column bases of red polished granite
