A floating artificial island built in Mexico by British artist Richart "Rishi" Sowa. He's first Island was destroyed by a hurricane in 2005; a replacement, Joyxee Island, has been open for tours since 2008.
In the waters of Isla Mujeres, the "Island of Women", near Cancun. It opened for tours in August, 2008.
The new island was initially 20 metres (66 ft) in diameter, which has since expanded to 25 metres (82 ft), and plants and mangroves are already growing on it. It contains about 100,000 bottles. The new island has three beaches, a house, two ponds, a solar-powered waterfall and river, a wave-powered washing machine and solar panels. Volunteers helped with the project. Sowa will continue to make improvements to the Island, so it will always be a work of art in progress.

Spiral Island has been featured in a number of newspapers and TV documentaries around the world, including in Japan and South Korea, and has been featured in an episode of the Ripley's Believe It or Not! TV series, and on the MTV program Extreme Cribs in 2011.
