No precise coordinates have ever been established. The buildings simply fell, and the ground moved on around them.

The area was part of the manor of Colon in the fourteenth century, according to the historian F.E. Ball, writing in 1903. A great portion of those lands was wooded, which gave rise to the placename Cullenswood, the wood of Colon. The complex of buildings associated with the Archbishop, comprising at minimum a hall, a private chamber, and an attached chapel, was already ruined by 1326. Who caused the destruction, and under what circumstances, the record does not say. What it does confirm is that an ecclesiastical presence of some significance once existed in this part of south Dublin, in a landscape that would have looked nothing like the Victorian red-brick suburbs that eventually replaced it.

Because the site has never been precisely located, there is nothing specific to visit. The modern areas of Ranelagh and Sandford occupy the general territory, and Cullenswood itself is recalled in street names and in the occasional local history. Anyone curious about the area might find value in reading Ball's account directly, or in walking the neighbourhood with the understanding that medieval Dublin extended further into what feels like settled, unremarkable suburbia than most maps suggest. The ruins, if any trace survives below ground, have never been the subject of a dedicated excavation, and their exact position remains an open question.
