The Dakeen Monastery was a religious retreat on Bajor.
During the Occupation of Bajor, Vedek Bareil Antos visited the monastery during the time surrounding the Kendra Valley Massacre, and during his visit, he had virtually no communication with the outside world. Kira Nerys was able to use the transit logs and communications records to verify that Bareil was not a collaborator, despite his own claims to the contrary. (DS9: "The Collaborator")
During a discussion about Bajor with Vice Admiral William Ross, Captain Benjamin Sisko considered visiting the planet for a week of two following the end of the Dominion War. During his visit, he hoped to visit the Dakeen Monastery. (DS9: "Favor the Bold")
