The site of St Bridget's Well at Gracedieu, in north County Dublin, is a rather different case. By 1958, a survey found that no tradition about the well survived in the locality at all. By 1975, there was nothing to be seen at the surface. By the early 2000s, the well itself had been backfilled for safety reasons. What remains is, in effect, an absence, a place that was once considered sacred enough to name, and is now a slight dampness in a field.

The well sat in a partially reclaimed paddock, roughly 50 metres north of a corn mill and 150 metres east of the Gracedieu Augustinian Nunnery, a house of Augustinian canonesses whose ruins still survive nearby. Holy wells dedicated to St Bridget are common across Ireland, typically associated with healing or with the saint's feast day on the first of February, but this one had already lost whatever ritual life it once held before anyone thought to record it properly. When Caoimhín Ó Danachair documented it in 1958, local memory had already gone blank. A field visit by Henry A. Wheeler in May 1975 found only a small, wettish field beside a derelict farmstead and the old corn mill, with no visible trace of the well. Wheeler noted that modern drainage works had likely lowered the water table across the area, drying up wells that had previously fed from it. A second holy well, Lady Well, lies about 220 metres to the south-south-west, and a stream still rises to the east of the site, suggesting the ground was once considerably wetter.

There is no surface feature to locate or examine here, and the well itself has been backfilled. The value in knowing about this site is less about what a visitor might see and more about what the record reveals: how quickly a sacred site can be forgotten, how drainage and agricultural improvement can erase the physical conditions that gave a place its meaning, and how the act of documentation sometimes arrives just in time to record a disappearance rather than a survival. The area around Gracedieu does retain the nunnery ruins and the remains of the corn mill, which give some texture to the landscape, and the broader townland repays quiet exploration for those interested in how densely layered even unremarkable-looking ground in County Dublin can be.
