King of the hard end

Highlight • Other

It is at the end of a climbing and winding road that we discover the small church of Saint-Yon, and its adjoining cemetery. Here rests, under an ancient mausoleum, Maurice MOREL (1885-1972), better known as the "King of the Hard End" in reference to the metal reinforcement he invented for safety shoes which made his fortune. .

Porte des Bourdeaux...

Highlight • Other

The place takes its name from Saint-Yon, a Christian martyr beheaded by Roman soldiers on this hill. The church and the Porte des Bourdeaux are the remains of a village whose strategic position made it possible to monitor the Orge valley and the Brie plain.
