Over the arch there is a statue of the Holy Father holding out his crucified son for the world to see.
In the Breton language these entrances are called "Porz ar maro" ("The gate of the dead").
Of these statues, that of John the Evangelist and James the Greater have been attributed to Roland Doré.
[1] These date to the 17th century and are in front of an altarpiece depicting Jesus' baptism and John the Baptist's parents Zacharius and Elizabeth.
There is also a statue of Saint Sernin holding Jesus' robe whilst he is baptized.
[1] The sculptor Jean Cévaer and the carpenter Jeané Le Seven combined to produce the "Rosary" altarpiece in 1696/98 and at a later stage the painter Olivier Grall added paintings.
A series of medallions spaced around the central tableau depict episodes from Jesus' life.
[1] In the centre of the church's chevet, there is a stained glass window depicting the Passion of Jesus Christ.
