The structure
The church lies north of a cloister court, with domestic ranges around it. Parts of the church and south range rise above the lower foundations; carved details survive among the pink and grey masonry.
Its story
Founded around 1200, the nunnery’s first prioress was Bethoc, also known as Beathag. Fifteenth-century alterations enlarged parts of the complex. Later repairs stabilised the ruins, including work in the nineteenth century and 1920s.
Why it is included
It gives women’s monastic life a distinct architectural presence alongside the better-known abbey.
What to look for

What we know — and what remains uncertain
The date and reason for hiding the objects are unknown. The nunnery’s post-Reformation history is patchy, and not all of its western range has been archaeologically tested.
