Karl Ullger has explored 90,000 years of geological change on Gibraltar’s eastern coastline through a triptych and a 3D-printed sculptural model created for the Traces of Humanity exhibition. The work, centred on Gorham’s Cave, examines how Gibraltar’s coastal shelf has changed over time and considers how vegetation and habitats once extended miles beyond the cave’s present-day entrance. The three-panel artwork combines landscape painting with sculptural interpretation to present Gibraltar’s coastline as an evolving geological story. The final panel moves away from traditional representation, presenting a 3D interpretation of the coastal shelf extending from one metre to 4,500 metres offshore. “By compressing millennia of geological change into a compact object, the piece invites close inspection and reflection on Gibraltar’s vulnerable coastal threshold.”
