the arch near to ground level are the piédroits and the remaining wedge-shaped stones used in constructing an arch form the voussoirs. Above the biblical scenes in the arch's piédroits are depictions of the four Evangelists and their attributes, with Saints Luke and John positioned on the left and Mark and Matthew positioned on the right and finally a "heavenly choir" of thirty one winged angels are shown floating in the clouds and praying, singing, playing various instruments or holding censers. Above the entrance arch is a gable in the Gothic style and on this the sculptors placed a statue depicting a female saint reading a book and another female saint higher up has her hands crossed against her chest. The gable is also decorated with two lions supporting the blason of François de Tournemine. Above the gable there is an ornate lantern with three niches. The central niche contains a statue of Saint Thuriau to whom the church is dedicated. The two buttresses supporting the arch have niches containing statues of the four Evangelists each seated at a desk with their attributes at their side. The buttresses also hold a statue of the Virgin of the Annunciation and another depicting Saint Anne with the Virgin Mary. All these statues are by Bastien Prigent. The inside of the porch is vaulted and is decorated with the blason of the Danycan family and Henry Prigent added statues of "Christ the Saviour" and the twelve apostles in niches each with an elaborate canopy. The heads of these apostles were damaged during the turmoil of the French revolution and bear signs of restoration and some of the attributes were destroyed which makes identification difficult. The arches around the two doors giving access to the church are in turn richly decorated with garlands of thistles ("chardon") and grapes and a series of statuettes in niches, these depicting Saint Yves, Saint Peter holding a book and a key, Saint Salomon the Breton king wearing armour, holding a sword and the royal crown, Saint Miliau carrying his head in his hands, Saint Thivisiau, a bishop, Saint Côme holding a vase containing medications, Saint Damien (Côme and Damien were brothers and both doctors martyred under Diocletian), and another bishop giving a blessing. On the left side angels hold a cartouche reading "ANNO.DOMINI.1554" and on the right the cartouche reads "LAN.MIL.VCC.L1111.FVST.FONDE.CESTE.PORTAL.ET.ESTOIENT.LORS.FABRIQVES.Y.MART(I)N.J.ABGRALL". Above the doors a tympanum depicts angels
