Chartres Cathedral, also known as the Cathedral of Our Lady of Chartres, is a Roman Catholic church in Chartres, France, about 50 miles southwest of Paris. Mostly constructed between 1194 and 1220, it stands at the site of at least five cathedrals that have occupied the site since Chartres became a bishopric in the 4th century. It is in the Gothic and Romanesque styles.  The cathedral attracts large numbers of Christian pilgrims, many of whom come to venerate its famous relic, the Sancta Camisa, said to be the tunic worn by the Virgin Mary at Christ's birth, as well as large numbers of secular tourists who come to admire the cathedral's architecture and historical merit.
