Prince Charles and the Duchess of Cornwall will visit Pembrokeshire’s Melin Tregwynt today (Monday) as part of their annual Welsh tour.

The prince, who is patron of The Campaign for Wool, will meet staff members engaged in design, weaving, stitching and dispatching during a tour of the woollen mill near St Nicholas in North Pembrokeshire.

The whitewashed woollen mill has been owned by the Griffiths family since 1912 and currently employs around 30 people. Set in a picturesque and remote wooded valley on the Pembrokeshire coast, a mill has been located on the site since the 17th century.

Over the years, the Griffithses have embraced change and new techniques, while retaining the key heritage features of the mill. The mill's water wheel has been recently restored by a local engineering firm with the help of a grant from Visit Wales.

Today, the mill designs and produces Welsh woollen textiles for a range of clients including John Lewis, Heals and Liberty. It employs an apprentice under the Creative Skillset Cymru Fashion and Textiles apprenticeship scheme.

After touring the mill, the royal couple will join textile company employers, Creative Skillset Cymru Fashion and Textile apprentices and employers and traditional woollen mill representatives at a reception.

The visit is part of The Prince of Wales's continuing commitment to raise awareness about the unique, natural and sustainable benefits offered by wool.

Launched by The Prince five years ago, The Campaign for Wool encourages collaboration between an international community of woolgrowers, major fashion designers, retailers, manufacturers, artisans and interior designers.

The Campaign has been instrumental in educating consumers about the versatility of wool, and reconnecting them with its myriad uses – from luxurious fine merino knitwear to fire-retardant insulation for the home. Since its launch.

The Campaign for Wool has influenced a new demand for wool on an international scale.
