Backed by thrusting, snow-capped mountains in the boondocks of southeastern Alaska, this domed, white-washed building is quite a sight. As its name suggests, it was modelled on an igloo and was originally supposed to open as a hotel – however, its failure to meet building codes meant the project was halted and visitors never came through the doors.

It sits just off Parks Highway near Denali National Park, smack bang in the middle of Fairbanks and Anchorage, and has been ultimately left to the whims of Alaska's wild weather. In 2023, there was talk of it being turned into a distillery.
