Mordhaus Is the giant citadel/Viking longboat where the members of Dethklok live, their recording studio, and all the equipment needed to work everything from producing their records, to maintaining and training their elite guard/roadies, the Klokateers. It suffered some damage caused by an angered Toki Wartooth in "Dethkids", but no real repair was needed. Later, Mordhaus was burned down by the Revengencers in "Black Fire Upon Us". It took at least nine months to rebuild Mordhaus, which was floating in the air in order to avoid no more damage. Mordhaus was nearly destroyed again when it plummets and almost crashes due to Dethklok not paying the electric bill.
Mordhaus Tours is a video tour of Mordhaus (hosted by Facebones), that appears as hidden DVD extra on the Metalocalypse Season 1 DVD. In it Facebones gives the viewer a video tour of Mordhaus.

The location of Mordhaus has never been discussed or even mentioned in the show, despite the fact that most of the action takes place there and it appears in every episode. However, some clues within the show point to the possibility that it is located in Northern Europe.For example, in Snakes N' Barells II, the band journeys from Mordhaus to the US with a red line tracing their progress across the map, and it enters the US from the Northeast from across the Atlantic Ocean. In Dethtroll, they are able to go to Finland by bus, indicating that it is geographically close to Mordhaus. In Fatherklok, Skwisgaar is able to fly to Sweden on a small flying device probably meant for short range flight. In Doublebookedklok, the band members run away to a snowy arctic region on foot, meaning it is fairly far north. Because it is known not to be in Norway (because Toki has to go there in Dethdad) or Denmark (because Skwisgaar is known to hate people from Denmark) and because the name itself is taken from the German language, this leaves Germany as the most likely candidate for the home nation of Mordhaus.
- The completion of an album is signaled to the fans when the chimney smoke from Mordhaus turn from white, to black.
- 'Mordhaus' is the german word for 'Murderhouse'.
- There are 7491 or 7492 rooms in Mordhaus.
- As of Season 3, Mordhaus is currently a flying fortress. In "FatherKlok", Skwisgaar Skwigelf is seen using a personal flying vehicle to leave the floating Mordhaus.
- The Mordhaus shown in the series is actually not the first the band has called home. In the Season 4 episode "Dethcamp", Mordhaus is shown to be a trashed-out apartment/practice space in a low-rent complex with "Mordhaus" spray painted above the entrance.
