Rottehullet (The Rathole) was the pub opposite huset in the danish TV-show Huset på Christianshavn where the male residents daily meet to drink and discuss or solve a problem.
The building has never been a pub, but the sign from the show still hangs there today and is one of the most visited locations on Christianshavn.
