It is impossible on the average computer screen to fit in a plan of the complete tomb so that the various captions are readable, so the following diagram is the best way of getting the terminology straight.
To see a full-size version of this plan using Zoomify, click on the picture.
Rear room or Shrine, with 5 shafts
Front room, with 1 possible shaft and two loom-related emplacements (interior)
Courtyard, with 3 shafts and remains of possible walls at the east end
NOTE: depending on the setup of the fonts in your browser, and the browsing software itself, the captions might not align properly with the parts of the tomb.
