Pembroke Castle: The hunt for clues to Wales' prehistoric past
Beneath Pembroke Castle, a cave is being excavated by archaeologists looking for clues to Wales' prehistoric past.
Reindeer and mammoth remains were among the Ice Age artefacts unearthed in Wogan Cavern.
Paleoecologist Elodie-Laure Jiminez called the site "pretty uncommon" as cave sites are not often found.
Devon Speleological Society archaeologist, John Boulton, added: "What we're really looking for is human occupation during the ice age."
