If you are into spotting the northen lights, check out this igloo village at Hotel Kakslauttanen in Finland. With a clear dome you can lay there and watch them to your heart's content.

Here is an official description from the hotel’s official web page:

Glass igloo provides an one of a kind opportunity to admire the northern lights and millions of stars of the crystal clear Lapp sky in a comfortable room temperature. Built from a special thermal glass, the temperature inside the igloo always stays a normal level. It also prevents the glass from not getting white frosted, hence keeping the view clear even when the temperature outside drops to under -30°C. Every igloo is equipped with a toilet and luxury beds. (Emphasis mine.)
