Halo, Wind-powered sculpture in Central Park, Sydney, Australia
Halo is a wind-powered sculpture in Central Park that features a large yellow ring with a 12-meter diameter mounted on a silver mast. The work stands roughly 13 meters tall and rotates gently in response to wind currents.
The work opened in 2012 as part of a major redevelopment that transformed the former Kent Brewery site into a public space. Artists Jennifer Turpin and Michaelie Crawford created the kinetic installation as part of this urban transformation.
The work takes inspiration from the circular forms found in traditional brewing, reflecting how the site was once home to an industrial facility that shaped the local community.
The sculpture is located on Chippendale Green, a recreational area within Central Park that is open to visitors at no cost throughout the day. You can visit anytime and observe how the work moves in response to changing wind conditions.
The mechanism relies on ceramic balls made of zirconia that enable the ring to rotate with minimal friction. This specialized material was chosen to allow smooth, continuous motion even in lighter wind conditions.
