Chartres Cathedral, also known as Cathedral of Our Lady of Chartres (French:Cathédrale Notre-Dame de Chartres), is a medieval Catholic cathedral of the Latin Church located in Chartres, France, about 80 kilometres (50 mi) southwest of Paris. It is considered one of the finest examples of French Gothic architecture and is aUNESCO World Heritage Site. The current cathedral, mostly constructed between 1194 and 1250, is the last of at least five which have occupied the site since the town became a bishopric in the 4th century.

The cathedral is in an exceptional state of preservation. The majority of the original stained glass windows survive intact, while the architecture has seen only minor changes since the early 13th century. The building's exterior is dominated by heavyflying buttresses which allowed the architects to increase the window size significantly, while the west end is dominated by two contrasting spires – a 105-metre (349 ft) plain pyramid completed around 1160 and a 113-metre (377 ft) early 16th-century Flamboyant spire on top of an older tower. Equally notable are the three great façades, each adorned with hundreds of sculpted figures illustrating key theological themes and narratives.
