The walls of the “penthouse” granary were intact when Mummy House was found, as it
was protected by the overhang. The several small structures on the ledge were in ruins.
Only the wall stubs of ten rooms and two Kivas remain, but several of these rooms must
have stood two stories tall to allow access to the perfectly intact two story building above.
Fewkes found a well-preserved mummy there, from which the Mummy House got its name.

The Mummy House is directly below the Sun Temple.
