Chartres (Eure-et-Loir). Cathédrale Notre-Dame, travées occidentales et façade

Archaeological research during the restoration of Chartres Cathedral's western façade and nave (2010–2012) revealed critical insights into its construction chronology. The study established that the northern bell tower was likely built to the northwest of the 11th-century cathedral façade, possibly adjacent to a southern structure, clarifying long-standing questions about the site's evolution. By analyzing successive building phases, researchers reconstructed the sequence of architectural developments, providing a clearer understanding of medieval construction practices and the cathedral's structural history.
