The nunnery of St Bridget was probably in existence circa 1176 but there is no record of its foundation but it has been listed as being on the site of a keeill. St Bridget's name is also attached to a northern parish, its church, and seven ancient keeill sites elsewhere on the Island. The surviving chapel building, thought to date from around the 12th or 13th century, is the only monastic structure of the nunnery still standing; for centuries it served as a coach house before being restored to use as a place of worship in the 1880s. It continued in use as a chapel until 1998, when new owners of the estate ended the congregation's use of the building and it was deconsecrated.
