Abbey of Saint-Pierre-le-Vif

Before the 9th century there was in the cemetery near the monastery a group of tombs, among which are those of the founders of the diocese and the first bishops, Savinian and Potentian.

In 847, the transfer of their remains to the church of Saint-Pierre-le-Vif inspired popular devotion towards the two saints.

[3] In 1238, Baldwin II, Latin Emperor of Constantinople, sold the Crown of thorns to Louis IX of France.

The following year, during the royal progress of the relic to the Sainte-Chapelle in Paris, the court stopped at Sens.

[4] During the Revolution, Étienne Charles de Loménie de Brienne, who had signed the Civil Constitution of the Clergy, bought the former abbey and had the majestic church, burial place of his predecessors as Archbishop of Sens, demolished, installing himself in the abbot's house with members of his family.
