Someone awesome told me about this, and I wanted to share the news...
Apparently Helsinki, the recently announced World Design Capital for 2012, is to have the world's first underground city plan. The majority of the Finnish capital's centre can already be accessed through various underground links, and there are already a surprising amount of existing venues and utilities. These include central bus stations, which are located below street level and high-energy consuming data centers. Apparently the city has already over 9 million square meters of underground spaces!
With, as it seems, more to come....
