This is probably the largest landsculpture in the world: Michael Heizer‘s ‘City’ sculpture, Lincoln County, Nevada
It is under construction since 1972 and closed to the public. However when it will be finished, public access will be possible. It is said that Heizer is not amused by Google Earth revealing its exact location, as it triggers trespassers to visit the site before completion.
The New York Times ran an interesting article about Michael Heizer in 2005.
Those who helped in the construction:
- Chris Nason
- Andy McConnell
- Andy M, USA
- David Kozina
- Javier Abadia
- Steve Jaycocks
- Paul Franson
