Start to the left and exit in the classic version of Le Mur des Lamentations without using any of the holds of the classic version, before joining it at the larger crimps.
NB: A less eliminant 7c version is also possible.
NB: the joint last hold at the top of the wall of Le Mur des Lamentations, Gymnopédie and L'Éternel Retour au Sol is partially broken in the middle (february 2021). This makes all these problems slightly harder.
