St Govan was a hermit, possibly from Ireland and disciple of St Ailbe. He found a tiny cave for his cell in the cleft of the cliffs south of Pembroke. A church for pilgrims was built over the opening of the cave in 11C, or even earlier. His body is said to lie beneath the altar.
Bearer of Light in the West of Wales
You hid in your cave for the sake of prayer
that the Gospel may spread in Dewisland,
O holy St Govan cease not to pray
that once more Christ may reign in this beautiful land
