It has no surviving stonework, no plaque, and no fixed address. Scholars cannot pinpoint exactly where it stood. What remains is a name, a few archival references, and a small puzzle that quietly resists being solved.

The gate appears as Gate E8 on H.B. Clarke's authoritative map of medieval Dublin, covering the period roughly 840 to 1540, published as part of the Irish Historic Towns Atlas series by the Royal Irish Academy. It was already known by name in 1577, when Richard Stanihurst listed it as 'the Newstreet gate' in his Description of Dublin. By that point the gate was presumably a long-established feature of the city's southern boundary. Its memory surfaces again in a 1662 lease between the vicars of St Patrick's Cathedral and a man named William Williams, concerning a plot of land called Baugon's Park. The lease is unusually precise: the parcel measured 116 yards east to west and 100 yards north to south, with 30 of those yards lying within New Street Gate and the remaining 70 outside it. This detail is remarkable because it places the gate not at the very end of a street but as a threshold through which property extended, a gateway that divided a single piece of land rather than simply closing off a road. The vicars of St Patrick's, it should be noted, were the clerical staff attached to the cathedral who held property on its behalf, and their involvement here reflects how closely the Church's landholdings were woven into the medieval street plan of this part of the city.

New Street itself still exists, running south from the junction near St Patrick's Cathedral towards the Coombe. A visitor walking its length today will find a fairly unremarkable urban street with no visible trace of any fortification. The general area around the southern end is worth examining slowly, partly for what it does not show. Bradley and King's 1987 survey noted simply that the gate's precise location has not been identified, and that remains the position. The Irish Historic Towns Atlas map, accessible through the Royal Irish Academy, is the most useful tool for placing the gate in its wider context among the other known entry points of medieval Dublin.
