The Nunnery of St Bridget was probably in existence circa 1176 but there is no record of its foundation. By an indenture of 1532 the nunnery was vested in the crown and by 1610 became the property of the Earl of Derby. St Bridget's, the Nunnery Chapel, is now the only building which survives of the 12th and 13th century buildings and had long been used as a store-room and coach-house. It was restored in 1887 by Mr Leigh Goldie-Taubman. Evidently it belonged to the later Priory on this ancient site. Unfortunately no particulars of the original buildings have been recorded. The inscribed fragment of an oak-beam now in Manx Museum is believed to have been a rood-screen in the Chapel.


St Bridget's was brought back into temporary use as a chapel about 90 years ago. It had previously been used as a coach house and is now in very occasional use as a private chapel. The chapel is orientated east to west and measures 18 metres by 7 metres, stone-built with a modern roof.  The north wall has been considerably patched and has one large ashlar framed, arched window which may be original and two modern red sandstone framed windows. The east wall has a wide, rectangular, blocked-in doorway and above it an ashlar framed, arched window, largely restored.. The south wall has mainly modern ashlar framed windows and doorway, but has one long narrow ogee window framed with brown and red sandstone and an original arched brown sandstone window partly restored. The interior is equipped as a Catholic Chapel and is in a good state of preservation. The west wall is masked by a modern building. The piscina and pilasters were seen in the interior of the chapel.
