Oh, how I wish these weren't abandoned. Sanzhi Pod City in Sanzhi District, New Taipei City, Taiwan, looks like something straight out of the Jetsons. The complex of pod apartments was built in 1978... or, almost built. The funding went awry and now all that's left are these futuristic-looking ruins. Retronaut has a great gallery of the place if you'd like to see more. http://www.howtobearetronaut.com/2011/06/abandoned-pod-city/

However, just two weeks ago, I visited a similar one in Taiwan with a similar set up.
