Monastery

A monastery is a religious retreat, usually isolated, and normally home to monastic groups devoted to the ideals of their order. Monasteries are prevalent throughout the races of the Alpha and Beta Quadrants, particularly among those races with more spiritualized societies.

In 2151, Captain Jonathan Archer claimed that the oldest monastery that he ever visited was in Ngari, Tibet. 

While visiting Earth during the mid-22nd century, Doctor Phlox attempted to familiarize himself with many of the planet's religions including Buddhism, which he accomplished by spending two weeks at a Tibetan monastery where he learned to sing chords with the high lamas. 

The Vulcan monastery at P'Jem was already a thousand years old by the 22nd century and was still used by Vulcan monks prior to its destruction by the Andorians. 

The Klingon monastery at Boreth is central to the legend of Kahless the Unforgettable and his promised return. In 2369, Worf visited the monastery in an attempt to rediscover his Klingon heritage. It was there that Kahless apparently returned from Sto-vo-kor, although it was later revealed that he was a clone. Worf visited the planet again in 2371 following the destruction of the USS Enterprise (NCC-1701-D). 

Bajor, with its highly religious people, is home to several monasteries, including the Monastery of the Kai and the Dakeen monastery. 

Odo once claimed that Risa made the Trill Hoobishan Baths look like a monastery. 

Tom Paris threatened to send The Doctor's character in the Fair Haven holoprogram, Father Mulligan, to a nearby monastery with a vow of silence.
