During January 2019, cave divers conducting line-laying training recovered two vessels, one complete and intact, the other was fragmented but mostly complete. An intact single-handed flagon, the form is of late third to fourth century date, broadly similar to New Forest grey ware products. The second vessel, an Oxford Red-slipped Colour Coat flask with a globular body, tall, narrow neck and plain rounded rim with a shallow groove below the lip, dating to the fourth century. Although unstratified, it is highly probable that the two vessels are derived from disturbed late Roman inhumation burials within the Fourth Chamber.
