Cromwell's Well at Ballyvada sits, or rather once sat, at the base of a steep north-south precipice on the eastern bank of the River Suir, roughly fifty metres from the water itself. It no longer surfaces in any visible form; what remains is a loose cluster of stones, roughly four metres square, in approximately the spot where the well appears on the first Ordnance Survey maps of 1843 and again on the revised edition of 1900 to 1905. The stream that once ran from the well and flowed south-west into the Suir is now buried under rushes, flag irises, and encroaching scrub.

The well appears to have been a natural spring rather than a constructed feature, though it shares the slope with Suir Castle, a tower house, the kind of fortified residential structure common across late medieval Ireland, which stands above on the edge of the same precipice. The association between the two is plausible but unconfirmed; wells were frequently linked to tower houses for practical reasons of water supply, and this one's position directly below and to the north-north-west of the castle makes the connection geographically tidy. What the name Cromwell's Well actually records is harder to pin down. Across Ireland, Cromwellian associations were attached to countless landscape features during and after the seventeenth century, sometimes accurately, often as a form of folk memory that simply needed a familiar villain to explain something old and unexplained. Whether the name here reflects a genuine episode or simply that habit of naming is no longer recoverable from the site itself.

The slope where the well once lay is overgrown and the feature is, by any current account, invisible on the ground. The distinctive stone cluster is the only marker that might indicate where it was. Suir Castle above remains the more legible part of the picture, occupying the top of the same precipice and offering a clearer sense of how this small, layered corner of the Suir valley once functioned.
