The precise location has been lost to time, swallowed by the gradual expansion of the city and the selective amnesia that tends to settle over sites of public execution. What survives is little more than a footnote, a single reference in a local history, enough to confirm that the structure existed but not enough to pin it to any particular street corner or field boundary.

The source for this is F. E. Ball's historical work of 1906, which places a gallows at Harold's Cross during the eighteenth century. Gallows were a familiar feature of the pre-modern urban and suburban landscape, typically erected at the edges of settlements where they could be seen by travellers approaching a town, serving as a public warning as much as a site of punishment. Harold's Cross at that period was not the built-up inner suburb it later became, but a village on the road south from the city, surrounded by open ground. The gallows would have been unremarkable to contemporaries, a routine piece of civic infrastructure in an era when hanging was the standard penalty for a wide range of offences, from murder to theft. That it stood here is almost certain; that nobody recorded exactly where is entirely typical.

There is nothing to see at Harold's Cross today that relates to this structure, and no marker commemorates it. The area is now densely residential, centred on the green and the roads leading toward Rathmines and Terenford. For anyone curious about the site, Ball's 1906 history remains the only documented reference, and even that gives no coordinates beyond the name of the village. It is the kind of place that rewards a particular sort of attention, not the search for a visible relic, but an awareness of what the ordinary streetscape was once required to contain.
