The most visible 18th century addition to the basilica is the spectacular funeral monument for Princess Maria Flaminia Odescalchi Chigi, the young wife of Don Sigismondo Chigi Albani della Rovere. It was designed by Paolo Posi in 1772 and sometimes dubbed the "last Baroque tomb in Rome". By the time the church was full of valuable tombs and artworks, and there was not much room left for the 19th century. Nonetheles there were smaller interventions: the Cybo-Soderini Chapel was restored in 1825, the Feoli Chapel was completely redesigned in Neo-Renaissance style in 1857 and the monumental Art Nouveau tomb of Agostino Chigi by Adolfo Apolloni was erected in 1915. After that only repairs and restorations happened regularly; the first important modern intervention was conducted by Antonio Muñoz in 1912 with the aim to "restore the church to its beautiful quattrocento character" and removing many of the Baroque additions in the nave and the transept.
