The Rose window, that inspired poem is from 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 a UNESCO 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.
