It is located in the "pays bigouden", a particularly wind swept area of Brittany; the nearby chapelle was called the "cathédrale des dunes".
The calvary dates to between 1450 and 1460 and stands on the grass verge ("placitre") in front of Saint-Jean-Trolimon's Notre-Dame Chapel.
It is the oldest of Finistère's six "grands calvaires" and is thought to be the work of several workshops operating in Scaër, mainly that of the "Maître de Tronoën".
It replaced an ancient Romano-Gallic temple dedicated to the goddess Venus (mythology) and was thought to have been commissioned by the Pont barons.
The calvary comprises a large rectangular granite pedestal or base which measures 4.50 m by 3.15 m. Around this base are two friezes on which are various sculptures, single or in groups, which recount some incidents in Jesus' life beginning with the Annunciation when the Archangel Gabriel tells the Virgin Mary that she is pregnant with Jesus Christ.
At the base of the cross on the right of Jesus' cross is a sculpture showing St Veronica holding up her veil bearing Jesus' image and on the left is a depiction of James, son of Zebedee, wearing the typical dress of a pilgrim to Santiago del Compostella, a pilgrim's staff and a sea-shell worn on his chest.
[2][4] The scenes on this face of the calvary are in granite and in high relief and deal with Original sin, the Resurrection and the Last Judgement.
The first positioned on the left depicts Pontius Pilate washing his hands as Jesus, held by two soldiers, is brought before him.
