What you should know about Square Jean XXIII.
Square Jean XXIII is best known for being created between 1844 and 1848 on the former grounds of the Archbishop's Palace after the palace was demolished following the 1831 anti-clerical riots, becoming the oldest public garden in Paris before Haussmann's great urban transformations, later being renamed in 1970 to honor Pope John XXIII while preserving unrivaled views of Notre-Dame's flying buttresses, the neo-Gothic Fontaine de la Vierge completed in 1845, and one of the cathedral's most celebrated architectural perspectives.
The garden transformed a site once occupied by ecclesiastical buildings into a public space that has welcomed generations of Parisians and visitors alike. Carefully preserved landscaping continues framing the eastern elevation of Notre-Dame with remarkable sensitivity, allowing visitors to appreciate the cathedral's structural ingenuity while experiencing one of the city's earliest purpose-built public gardens in an atmosphere of quiet reflection.
