Hinzerhaus is a houe-fortress type citadel on the planet Jago. It's primary purpose was once for defensive fortification, although it contained a number of living conditions for it's former residents. The true nature of Hinzerhaus's builders is still unknown, though it is believed that it is a matter for the Ordo Xenos.

Hinzerhaus was used by the Tanith 1st during their battle with the Blood Pact in 778.M41, where it revealed its rather sinister properties and ancient mysteries. It's value as a defense was tempered by the psychological effect that the rotting house had on the troops at it's bunkers.
