The chancel
In the late 12th century, the original short, flat apse was replaced by a vast sanctuary with a deambulatory and radial chapels, making Pontigny the largest surviving Cistercian church. The still hesitant technique of the nave gives way here to a perfectly conceived Gothic style. In the middle of the first bay, a tile decorated with three fleurs-de-lis marks the site of the tomb of the French queen Adèle de Champagne, mother of Philippe Auguste, who died in 1206.

The quotation
‘Here are those whom God
loves as his children,
and whose Wisdom,
like living stones,
builds himself a temple.
So that nothing can shake
this edifice that God inhabits
and builds at the same time,
they are cut like stones:
above,
when they submit their will
to God's will with humility and prudence;
underneath
when they govern with temperance
the flesh they have subdued;
on the right, when they embrace
the good with justice ;
on the left, by supporting
the wicked with strength’.

The vaults in the sanctuary are built on ribbed vaults, all of which rest on a succession of capitals, columns and bases, in accordance with the grammar of the Gothic style. The high windows are crowned with multiple arches, necessitating a multiplication of columns.
Alongside the sober but varied capitals of the nave, those of the chevet seem more refined but more repetitive. The keystone above the roundabout, with its ten ogival branches, evokes an idealised flora.
