It crossed a stream that once ran to the north-east of the Liffey, a watercourse that has long since been culverted, built over, or simply forgotten as the city expanded around and on top of it. The bridge itself exists now only in the documentary record, a cartographic footnote to a medieval landscape that bore very little resemblance to the one visitors walk through today.

The clearest evidence for its existence comes from two sources. It appears on the Friends of Medieval Dublin Map, published in 1978, which attempted to reconstruct the layout of the medieval city using surviving records, archaeology, and topographical analysis. It is also cited by Bradley and King in their 1987 survey of Dublin's medieval urban archaeology, where it is catalogued as entry number 33 in volume three. Neither source provides extensive detail about the bridge's construction, date, or precise function, but the combination of cartographic and bibliographic references is enough to confirm that this was not simply a notional crossing. A stream of sufficient size to warrant a bridge would have been a meaningful feature in the daily movement of people and goods through the medieval city, likely connecting areas of settlement or commerce on the south bank with routes leading towards the Liffey.

There is nothing to see here in any conventional sense. The site carries the designation of no visible surface trace, which in archaeological terms means that ground-level inspection will yield nothing. The stream is gone, the bridge is gone, and the streets above give no indication that anything of note lies beneath. For anyone interested in the medieval topography of Dublin, the value of a site like this is partly conceptual: it is a reminder that the city's current street plan is layered over an earlier one, and that the routes people walked in the twelfth or thirteenth century were shaped by watercourses that no longer exist in any visible form. The Friends of Medieval Dublin Map, available through libraries and some online archives, remains the most useful tool for situating this kind of vanished feature within the broader pattern of the old city.
