inspired and powered by nature

Aluna will be the world’s largest Moon and Tide Clock planned to open at 0° longitude on the Greenwich Peninsula in 2023. At 40m wide and 13m high, larger than Stonehenge, Aluna’s distinct shape is formed of three vast translucent recycled glass rings representing the lunar phase, the lunar day and the tide cycles. Light slowly encircling the piece tracks the waxing and waning of the Moon, its movement across our sky, and the ebbing and flowing of the tidal Thames.

The National Oceanography Centre has designed Aluna’s master time code to tell the world’s most accurate lunar time, and Aluna’s geometry relates precisely to its function and is unique to its Greenwich Meridian location.

Aluna will showcase the best in regenerative design, innovation and engineering: built from 100% recycled glass and steel, illuminated by low energy LEDs and powered by the Sun and Moon using onsite solar panels and tidal turbines. Aluna will be upgradeable for future generations and eco-engineered to enhance the Thames’ intertidal habitat.

Designed by artist Laura Williams as a place of celebration and connection, Aluna’s rings will create a large public space for international festival, education and community events… or just to enjoy quiet reflection on the banks of London’s magnificent tidal River Thames.
