Local reports document the discovery of numerous brass pins scattered throughout the sand, alongside deposits of slag; telltale signs that this quiet stretch of coastline once hummed with metalworking activity. These findings hint at a forgotten chapter of Irish coastal industry, where craftspeople may have produced everyday items like pins and fasteners that were essential to medieval and early modern life.

The presence of slag, a byproduct of smelting and metalworking, suggests this wasn’t merely a site where finished goods were lost or discarded, but rather a location where active production took place. Brass pin manufacturing was a significant cottage industry in Ireland, with these small but essential items serving multiple purposes: from securing clothing and cloaks to fastening documents and textiles. The concentration of both pins and industrial waste at Portbane points to either a workshop site that has since been claimed by coastal erosion, or perhaps a dumping ground for a nearby manufactory.

Further along the coast at Dunree, archaeological evidence reveals another glimpse into Donegal’s maritime past through the remains of a midden. These ancient refuse heaps, built up over generations, serve as time capsules of daily life, preserving shells, bones, pottery fragments and other discarded materials that tell the story of the communities who lived and worked along these shores. Together with the Portbane finds, these sites paint a picture of a coastline that has long been home to industrious communities, adapting to and thriving in this rugged Atlantic landscape.
