The Cathédrale Notre-Dame de Chartres, or Chartres Cathedral, has long been the main reason why many people visit the town of Chartres. This superb Gothic cathedral has many outstanding features, but it is the collection of 2,600 sq. metres of stained glass windows that is absolutely unique and precious. There are over 150 windows which hold 5,000 images illustrating biblical stories as well as daily life in the 13th century. Whilst the stained glass windows will impress most visitors, don't forget to admire the Chartres Labyrinth, believed to the largest in the world.
