Pope Benedict XVI will bless a mosaic of St David with holy water from Wales during his visit to Westminster Cathedral next week.

He will sprinkle the mosaic with water from St Non’s well, a place of healing since the Middle Ages located on the wild cliffs of Pembrokeshire.

Canon Christopher Tuckwell, administrator of Westminster Cathedral, said it was part of the Holy Father’s “outreach to Wales and to the people of Wales”. The Pope is not able to visit Wales during his four-day trip.

The mosaic, which has only just been completed, was designed by Welsh artist Ivor Davies and made by Tessa Hunkin of London’s Mosaic Workshop.
