Behind an inconspicuous pair of doors in a city centre, lies a vault once used for royalty, wine and war-time shelter.
Castle Vault in Southampton was built in the 12th Century to store the King's wine at a time when the port was at the centre of the wine trade.
It was largely forgotten about until the 1770s when some builders accidentally knocked through, uncovering the historic space.
Radio Solent's Alex Hopwood ventured underground to learn more about the 800-year-old vault that lies beneath the Hampshire city.
Castle Vault is one of about 60 vaults that were built in Southampton between the 12th and 15th centuries.
