Sky Castle is a dreamy, interactive sound and light installation, featuring a cluster of inflatable arches that span in colourful symphony across public space.

As guests move through the arches, their movement powers and progresses the melodic xylophone soundscape stimulating colour changes in each arch. Light, colour and music have been orchestrated to evoke the joy and hope that rainbows bring after every storm.

As more people join the journey, the contemporary score crescendos in intensity creating a lush, orchestral piece that is different every night as it responds to crowd flow and fluctuations.

Sky Castle launched in Fed Square in 2020 to celebrate Melbourne’s emergence from its 3rd lockdown. A supersized, mega Sky Castle appeared in Shenzhen at the end of 2020, followed by Hong Kong in May 2021. Sky Castle has since toured nationally across Australia and around the world.
