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.{{Sfn|de Finance|2012|pp=12-13}}
