According to tradition, it was erected over the house of Senator Pudens, where Saint Peter has lived as a guest. Initially, during the 2nd century, thermal baths had been built on the site, and these were later converted into the church dedicated to Saint Pudenziana, daughter of Pudens and sister of Saint Prassede.
Ruins of the bath are still visible behind the apse, to the left. During the 8th century the church was rebuilt and then restored in the 11th, 12th and 16th centuries. In the apse is a fine 4th century mosaic.
