Fragment of a pillar slab from St Ninian’s Cave, Isle of Whithorn. It shows the remains of an encircled, equal-armed cross with a central depression. This appears repeatedly on St Ninian’s Cave sculpture, and is reminiscent of the encircled cross-of-arcs on 2. The stones from St Ninian’s Cave had all been moved from their original positions before discovery. The cave was probably an early medieval chapel. On display in Whithorn Priory Museum, Dumfries and Galloway.
