After surveying the trim and analyzing the paint, the team found that the arched doorways on the first and second floors both used elements that were once part of the ca. 1812 arched doorways.  On the first floor, the arched doorways in the Drawing Room appeared to have reused the lower elements from the doorways, including plinths, pilasters and paneled jambs. However, the upper, arched pieces of the ca. 1812 doorways were found to be reused on the second floor.  Why would the duPonts split up the trim between four different doorways instead of installing all of the pieces on just two doorways like the originals?
