An essential coastal landmark for navigation, it was for that reason restored and thus saved from destruction on Napoleon’s order in 1807.

A young linen maid who had worked on a holiday in the honour of the Virgin despite Saint Kirec's disapproval, became suddenly completely paralysed.

The chapel was called "Kreis-Ker" because it was located in the middle of a village, in the inner suburb of St Pol de Léon.

Some architectural features such as the "perpendicular style" at the base of the tower are obvious signs of an influence from across the Channel.

Settled on a long-term basis in St Pol de Léon after the war of succession of Brittany, the English converted the tower into a look-out post turned towards the sea and the surrounding countryside.

A magnificent specimen of "clocher à jour", the granite spire is an octagon pierced by 80 openings which reduce wind resistance.

The triangular pediment over the porch contained carvings of the coats of arms of many of the chapel's benefactors, but these were chiseled away during the French Revolution.

The porch leads to two doors giving entry to the cathedral and these are decorated with carvings of different kinds of foliage, monsters, domestic animals, griffons and chimeras.

The doors of the altar's tabernacle are decorated with bas-reliefs depicting the prophet Elijah in the desert and the sacrifice of Abraham, as well as the Last Supper.

That on the right represents Moses receiving the tablets whilst that on the left depicts the "serpent d'airain" and the camp of the Hebrews.

The Kreisker chapel holds a plaster maquette of a 1919 war memorial (French: monument aux morts) by the Breton sculptor René Quillivic.
