The domed vault on pendentives is, with only a few exceptions, peculiar
to the southwest of France. Striking in its boldness, this type of vaulting
directs weight successfully to the supporting pillars
and permits the opening of large spaces in the outside wall. This type
of vaulting occurs at Saint-Etienne
in Périgueux, in the cathedrals of Cahors, Souillac et Solignac,
and spread as far as Fontevraud Abbey in Anjou.
