Historical records place it precisely; a 1508 document mentions Walter Courcy, the sovereign of Kilkenny, granting the forge 'by Crokker's Corsse' to Nicholas oge faber on a 50-year lease for 4 shillings per year. Croker's Cross was located at the junction of the Parade, High Street and Rose Inn Street. Even more helpfully, a 1518 indenture in the Ormond Deeds refers to a property extending from the town's toll-house in the north to the 'common smithy' in the south, confirming its location.

Archaeological excavations behind this site on Ormonde Street have revealed substantial evidence of medieval metalworking activity. Archaeologist Judith Carroll uncovered large smithing hearths, a smelting pit and numerous dumps of metalworking waste, predominantly iron slag, in large pits. The plot behind the forge extended an impressive 130 metres westward from Pudding Lane all the way to the town wall, indicating the significant scale of metalworking operations in medieval Kilkenny.

Interestingly, excavations stopped at the formation level of the present multi-storey carpark development, meaning significant archaeological features likely remain preserved beneath the modern structures. References to the forge also appear in various 14th-16th century documents, showing its continuous operation as a vital part of Kilkenny's medieval industrial landscape over several centuries.
