The Prince of Wales and Duchess of Cornwall will be in Hay on Wye today visiting local businesses and perusing the wares at the town's Thursday market.
Among the stops on the Royal visit will be family-run country store FW Golesworthy & Sons, the town's largest bookshop Richard Booth's Bookshop, the vacant Cheese Market and Hay Castle.
Prince Charles and Camilla will then tour the Hay Festival site, before joining authors at a School Library Association reception.
Prince Charles, in his role as patron of The Prince's Countryside Fund, will meet local farmers during the visit, while the Duchess will be introduced to schoolchildren at the launch of the Summer Reading Challenge.
The Royal couple will finish their visit by attending the opening night of the Welsh National Opera's new production of Wagner's 'Lohengrin' at the Wales Millennium Centre in Cardiff.
