The Rue Mondétour (French pronunciation: [ʁy mɔ̃detuʁ]) is a small pedestrian street in the 1st arrondissement of Paris.
[1][2][3] This street owes perhaps its name to the lords of Mondetour, and particularly Claude Foucault, Lord of Mondetour who was alderman of the city of Paris in 1525 under the provost master Jean Morin.
Other historians assume that the name of this street is an alteration of Rue Maudestour or Mauvais Détour ("Bad Detour").
