Even Sweden’s famous Ice Hotel is not exempt from fire regulations – this year’s installation of the hotel, built from scratch annually from snow and giant blocks of ice in the arctic town of Jukkasjarvi, included fire alarms and a built-in sprinkler system.

Sweden’s National Housing Board ordered the luxury ice hotel to install alarms to ensure the safety of guests – they weren’t concerned about the igloo-style building itself burning, but the reindeer skins, mattresses and pillows were a concern, Fox News reports.

Tourists flock to the hotel from all over the world to sleep in thermal sleeping bags on ice beds in temperatures as low as 17 degrees. Rates range from $200 to $500 a night.
