Recently, a curious object has been observed hovering over the terraced tea fields of Xia Yabai Village in the coastal province of Zhejiang, China. Surrounded by mountains, the picturesque village was established eight centuries ago, and though the place is steeped in history, it has lately become a haven for outdoor adventurers, with rivers, forests and farms that offer exceptional hiking, camping and agritourism experiences. A floating symbol of this contemporary condition, the large doughnut-shaped Sky Ring, designed by line+ studio, is part meteorological forecasting tool, part landmark — and a dynamic merging of technology, art and community.
The 30-metre-wide halo is made from a robust yet lightweight multilayered laminated composite. It’s filled with helium and tied to a concrete and rebar foundation by a tethering system comprising 16 synthetic-fibre anchor ropes. Integrated sensors measure real-time data like wind speed, temperature and air pressure; if conditions are favourable, the balloon ascends 25 metres to provide villagers and visitors with an unmistakable signal that it’s safe to venture out, and if they aren’t, a winch mechanism lowers the Sky Ring to the ground.

But more than a unique weather signifier, Sky Ring is also a destination in and of itself. As a new public gathering space, the inflatable circle encourages social interaction and community engagement from morning to night, when programmable energy-efficient RGBW LEDs illuminate the structure. Centrally located with panoramic views to the striking natural surroundings, Sky Ring injects a contemporary element into rural life and is a fantastic example of advanced technology and history colliding in a positive and inspiring way.
