Measuring roughly 22 metres north to south and 38 metres east to west, it is a compact space, yet it contains at least one object that quietly gestures toward the medieval city that once occupied this ground: a graveslab tentatively dated to the 13th or 14th century, making it among the older surviving funerary stonework in this part of the capital.

St Werburgh's itself is one of Dublin's older church sites, and the graveyard's attachment to its eastern end follows a familiar pattern in medieval ecclesiastical layout, where burial ground was typically arranged close to the body of the church. That this arrangement was already well established by the mid-eighteenth century is confirmed by John Rocque's 1756 map of Dublin city, which clearly shows the graveyard in its current position relative to the church. The graveslab within it, noted by researcher Joe Cully in October 2014, has not been formally dated through inscription but is assessed on stylistic or physical grounds as belonging to the later medieval period, a time when Dublin was a walled Anglo-Norman town and St Werburgh's stood near its administrative core.

The graveyard is not a destination in its own right in the way that larger Dublin burial grounds tend to be, and access depends on the church's opening arrangements, which are irregular. St Werburgh's is located off Werburgh Street, close to Dublin Castle, and the church itself occasionally opens for visitors, particularly in connection with guided heritage events. The graveslab, if you are able to get close to it, is the kind of detail that rewards patient looking rather than a quick glance; worn stone of this age rarely announces itself, and the interest lies in understanding what its survival in an otherwise modest urban churchyard actually represents in terms of continuity across seven or eight centuries of city life.
