French art collective Les Machines de L’ile is embarking on plans to build the world’s largest hanging garden – which will be on the scale of the Hanging Gardens of Babylon. The Nantes-based design team is currently working on what they are calling The Heron’s Tree – a massive interactive garden that will span more than 160 feet in diameter and 114 feet high. The “mechanical menagerie” will invite guests to climb the labyrinth-like branches and ride one of two mechanical herons on flights that provide a bird’s-eye view of the surrounding Loire Valley.

The Heron’s Tree, which is currently under construction on the banks of the Loire Valley, is actually the third part of a massive artistic endeavor called the Island’s Machines, which the artists began back in 2007. Inspired by the works of Jules Verne and Leonardo Da Vinci, the artistic project includes The Grand Elephant and the Machine Gallery, as well as the Carousel of Sea Worlds. The concept revolves around a mechanical collection of giant wild animals that roam around the world’s landscape.

The project will include a large steel tree, weighing about 1,500 tons and spanning 165 feet wide. Twenty-two wide branches will be built as walkways that will be accessible from a helix staircase inside the tree trunk. Jutting out from the trunk at various heights, visitors can explore the tree’s many greenery-lined paths, which create a lush ecosystem of hanging vegetation.

About 115 feet above the tree top, there will be two platforms where visitors can climb aboard two massive herons. The herons will take the passengers on a circular ride soaring over of the large tree, providing a stunning 360-degree view of the Loire Valley.

Created by artists Francois Delaroziere and Piere Orefice, the interactive art installation will be located on the banks of the Loire River – a significant location for the artists. “Inspired by the worlds of Jules Verne and Leonardo Da Vinci, it is an unprecedented artistic project. After the Grand Elephant and the Machine Gallery in 2007, the Carousel of the Sea Worlds in 2012, the Heron’s Tree is the third phase of the Island’s Machines. Coming out of the minds of François Delaroziere and Pierre Orefice, it will be located along the banks of the Loire River, a few meters away from the house Jules Verne spent his teenage years in and where Jean-Jacques Audubon grew up and drew his first herons.”

The Heron’s Tree is the latest phase in the art ambitious project, which is scheduled for completion in 2022. The 35 million euro project is being funding partially by public funds, but the artistic team behind the project is seeking additional funding through a Kickstarter campaign.
