This city in Minecraft took 400 people nine years to build

This Minecraft city is amazing.

For nine years, some rather industrious folks have devoted themselves to creating an impressive city called Greenfield in Minecraft.

The project started in 2011, and is still being worked on, and the latest update is set to be released on May 31. The project is maintained by ten people with many, many others - around 400 - who have jumped in to help create the metropolis (thanks, RPS).

Greenfield features a downtown area with skyscrapers, there are suburbs, industrial areas, public transportation such as railways and subways, and plenty of highways. Many of the buildings also feature an interior, and the team inspects each one to make sure everything is still working when a new build is released.

The city was built using a 1:1 Scale with one block equalling 1 cubic meter and takes up 20 million blocks. It's also only 20% complete.

You can get an idea of the scale of Greenfield by looking at the dynamic map through here. The video below also provides a look at the detail that went into the landscape and every building. You can also take a tour of the city yourself when May 26 comes around as the team will be hosting an open server event.
