After the
Jubilee of 1500, the association of bakers (Sodalizio dei Fornai) received permission from
Pope Alexander VI to build a church at this site. Construction of this church began in 1507 under
Donato Bramante, carried out by Andrea Sansovino and completed by
Antonio da Sangallo the younger. The design called for a square first story and an octagonal second story built in travertine and brick. It was one of the earliest domed square churches built on classical forms. Sangallo's facade is a maturer, more ornate version of the facade of the
Palazzo Baldassini. A second dome and lantern were added by
Jacopo del Duca around 1575. The church was built atop an earlier 15th century chapel, which contained an icon of the Virgin of
Loreto, hence the church retained the icon and acquired the title. It is most notable for the adjacent erection of a similarly domed, but pale marble, 18th-century church
Santissimo Nome di Maria al Foro Traiano, giving the semblance of twin churches. ==Interior==
