First classified monument to the world heritage by the Unesco in 1979, the cathedral Notre-Dame of Chartres remains the spiritual Mecca for the Christians who come to worship the veil of the Virgin (Virgo) there.
This masterpiece of the Gothic art is also famous for its collection of remarkable colored stained-glass windows, an heritage of the 12th and 13th centuries, particularly the Bleu de Chartres (the Virgin Cobalt Blue).
The old town, bordered by the Eure river, is remarkable for its bridges and medieval buildings and the Renaissance.
