On the third day of the annual summer tour of Wales, Prince Charles met local food producers and residents in Aberaeron, Ceredigion and Tregaron.
In Ceredigion, the Prince of Wales visited Llanrhystud Mill in Felin Ganol, which has recently been restored.
The mill produces organic stoneground flour and is the only working water-powered cornmill with original machinery in Ceredigion.
Meanwhile, the Duchess of Cornwall hosted a tea party on the couples' Llandovery estate for children and staff from the Ty Hafan children's hospice.
It is day four of Prince Charles's trip to Wales. Here is a photographic snapshot of his visit so far.
Prince Charles and the Duchess of Cornwall have visited St Asaph, Bodnant, RAF Valley and Aberystwyth on the first day of their tour.
Today, the first day of the Prince's annual summer visit, also will see him visit RAF Valley, St Asaph and the Conwy Valley.
