Chapterhouse was the term used by the Bene Gesserit for the planet considered to be their home base. The planet that 'Chapterhouse' referred to changed over the centuries of the existence of the Bene Gesserit. Speculation would put the original Bene Gesserit home base on the planet Rossak.

The planet was used as the secret headquarters of the Bene Gesserit is seen as a temporary base, and because of this the planet was never quite 100% settled and if needed, the Bene Gesserit could completely abandon the planet on very short notice leaving very little trace of their time spent.

Chapterhouse was on the same planet for more than 1,500 years, which means "temporary" headquarters was somewhat of a loose term.

The final planet was used as the Bene Gesserit headquarters from approximately the time of Leto II's death onward. They utilized No-ships in a defensive, encapsulating perimeter around the planet to mask its existence from prescient individuals who may be searching for the location of their headquarters, such as the Honored Matres.

The planet was largely in an average photosynthesis range, maintained through the use of Weather Satellites. However, after the planet Rakis was destroyed by the Honored Matres, the Bene Gesserit turned much of Chapterhouse into desert, so that the last surviving sandworm could survive on the planet. This was done so the spice melange could continue to be produced, which became all the more vital since the Bene Tleilax, the largest producers of melange, were also destroyed by the Honored Matres.

Chapterhouse was also where the Bene Gesserit maintained their main library. However, because the loss of information and historic records was far too great a risk, the majority of information kept by the Sisterhood was maintained through Other Memory.

Settlements in Chapterhouse included Central, where the Chapterhouse Keep was located, Pondrille and Eldio.
