The plans of this modern church from 1956-1962 (architect Josef Lantsoght) ars inspired by the 'kokkel'( a kind of mussel). Koksijde thanks its name to this mussel. At the origin a high tower was planned, but because of the near airport this could not be realised.
The inside of the church is very bright because of the many glass frames. GabriŰl Loire from Chartres has designed these glass frames.The vew of the altar is assured from evrywhere because of the constructionform. Altar and crusifix are from the hand of M.Witdouck.
When you enter the church you see immidiately that the blacks surfaces in the porche are in fact coloured glass, what creates a colorfull spectacle.
There is a beautiful sidechapelwith a modern Mary statue.
You would think that the confessional is part of the wall. It is situated near the organ.
Since 1968 there is a relic in the leg of the Holy Idesbald, which was 1155 the third abbot of the Abbey of the Dunes and a friend of the Holy Bernard of Clairvaux (one of the most influent abbots of the churchs history). On 18 july 1999 the relic was transferred from the crypt into the mausoleum in the church.
