The Saint‑Blaise des Simples Chapel dates back to the 12th century. Being the remains of a lazaret, it got through centuries to eventually be reborn unexpectedly under Jean Cocteau's paintbrush, for whom it is now the grave.
On a proposal from the National Commission of historical monuments, the Minister for Culture and Communication has, by order of May 6th 2015, ranked the St‑Blaise's Chapel historical monument.
Following a decision from the Milly-la-Forêt town council, taken on June 30th 2015, approval has been given to the Mayor to apply for a grant for a preliminary study to restore the frescos inside the Chapel.
