Solemnis was instrumental in the conversion of
Clovis. In 911, Bishop Gauscelinus used the
Voile de la Vierge (Veil of the Blessed Virgin), as a standard when warding off the invading Normans.
Fulbert was responsible for the advancement of the
Nativity of the Virgin's feast day on September 8.
Ivo of Chartres and
John of Salisbury were notable bishops. The
Cathédrale Notre-Dame de Chartres was constructed between 1194 and 1220, on the site of at least five cathedrals that have occupied the site since the Diocese of Chartres was formed as an episcopal see in the 4th century. In 1697, the
Diocese of Blois was erected from the territory of Chartres. It 1802, the Diocese of Chartres was suppressed, and the area placed under the newly created
Diocese of Versailles. However, in 1822, the See of Chartres was re-established and made suffragan at that time to the Archbishopric of Paris. ==Pilgrimages==
