Igloo City: As seen on Atlas Obscura
Igloo City, is a never opened and abandoned hotel shaped like a, well an igloo. (see listing on Atlas Obscure here).
Worth a Stop
It’s weird. It’s remote. If you’re driving between Talkeetna and Fairbanks it’s worth a stop for a few minutes as it’s really weird.
You can enter the Igloo, but it’s dark, dank and there is evidence of people camping / living / squatting there, so enter at your own risk.
