A renowned Aberystwyth artist has set a challenge for visitors to churches in Pembrokeshire this summer.

Martin Crampin has created a series of 16 ceramic tiles based on designs found in St David’s Cathedral.

Four of them are there on display as part of the annual Art on the Faith Trail, which was launched this week in the cathedral and runs until 31 July.

The other 12 are to be found in the eight other churches taking part in the exhibition, including St Peter’s, Little Newcastle; St David’s, Llanychaer; St Gwyndaf’s, Llanwnda; Holy Martyrs, Mathry; and St Aiden’s, Upper Solva.

When put together, they form the complete design. The challenge is to visit all the churches and piece them all together using maps and templates which are provided in each church.

Art on the Faith Trail is now in its eighth year. There is no overall theme; the artists select pieces of their work that they feel respond to the setting, the church or the cathedral.

The trail refers to the paths used by the travellers on pilgrimage in the early Christian world making their way to St David’s Cathedral.
