In 1901, the ca. 1812 arches that had been found on the south and north elevations of the Entry room were enclosed and new arched doorways were cut into the walls of the Drawing Room.  These new arched doorways were found on the first and second floors and where used to access new stairs built by the duPonts.  After discovering that the ca. 1812 arched openings were similar to the duPont arched doorways, the Investigation Team wondered if the duPonts’ carpenters had reused any of the trim from around Madison’s arched doorways for their four new arched doorways.
