Plan of the area around Notre-Dame signed by the architects Prost, Lelong and Godde, appended to the minutes of the handover by the State to the City of Paris of the Archbishop’s garden on 12 August 1842 (the legal text dates from 1837, but the actual transfer was not made until 1842).
It can be seen that the gates surrounded the square, trimming slightly to the east to extend the bridge with the street later called Quai de l’Archevêché.
Further east, a large part of the Square de l’Île-de-France and the Mémorial de la Déportation, reclaimed from the river, does not yet exist.
