For all of you wondering… kaelder is Danish for basement.
If that doesn’t explain enough, our house started it’s life as just a basement. It wasn’t until some time later that they had enough money to build the main level. Now the basement of our house is a scary place, complete with flocked orange and green wallpaper, cracked and broken floor tiles, and light switches outside of the rooms (along with the locks).
Some time in the future the basement will be brought back to it’s former glory but for now it’s a special place that I’m glad has a door that closes.
