small cemetery, but this cemetery no longer exists. The Parisian scholastic Jean de Jandun praised the building as one of Paris' most beautiful structures in his "Tractatus de laudibus Parisius" (1323), citing: Modifications (16th–18th century) The chapel underwent considerable modification in the centuries that followed. A new two-story building, the Treasury of Chartres, was attached to the chapel on the north side shortly after it was completed. It remained until 1783, when it was demolished to build the new Palace of Justice. Another building, which served as a vestiary and sacristy, as well as residence for the guardian of the treasury, was placed on the north side. In the 15th century, Louis X of France built a monumental enclosed stairway from the courtyard on the south side to the upper level. This was damaged by fire in 1630, rebuilt, but finally demolished. Fires in the palace in 1630 and 1776 also caused considerable damage, especially to the furniture, and a flood in the winter of 1689–1690 caused major damage to the painted walls of the lower chapel. The original stained glass on the ground floor was removed, and the floor raised. The original ground floor glass was replaced by Gothic-style windows in the 19th century. Revolutionary vandalism (18th century) Sainte-Chapelle, as both a symbol of religion and royalty, was a prime target for vandalism during the French Revolution. The chapel was turned into a storehouse for grain, and the sculpture and royal emblems on the exterior were smashed. The spire was pulled down. Some of the stained glass was broken or dispersed, but nearly two-thirds of the glass today is original; some of the original glass was relocated in other windows, The sacred relics were dispersed although some survive as the "relics of Sainte-Chapelle" in the treasury of Notre-Dame de Paris. Various reliquaries, including the grande châsse, were melted down for their precious metal. Restoration (19th–21st century) Between 1803 and 1837, the upper chapel was turned into a depository for the archives of the Palace of Justice next door. The lower of stained glass was removed to facilitate working light. Some of the glass was used to replace broken glass in other windows, and other panes were put on the market. Beginning in 1835, scholars, archeologists and writers demanded that the church be preserved and restored to its medieval state. In 1840, under King Louis-Philippe, a long campaign of restoration
