Dooku's prison

Dooku's prison was a prison consisting of various cells and torture chambers located deep within the rockface of a large cliff where Castle Serenno was situated on the Outer Rim Territories planet Serenno. At least one known entrance to the prison was a huge metal door flanked by controls in a long hallway in the palace. One of the cells in the prison featured a force field.

In 19 BBY, Jedi Master Quinlan Vos was held at the prison where he was tortured by Count Dooku and various droids. Former Sith assassin Asajj Ventress and Boba Fett's syndicate later attempted to rescue Vos however Vos by then fully embraced the dark side of the Force and spurned their rescue.
