Santa Maria in Domnica
Tradition holds that Numa Pompilius met the nymph Egeria on the site, and within the grounds of the present villa, to the left of the present entrance from piazza della Navicella, was the base of the 5th cohort of the Vigiles - these Trajanic-era remains were excavated in 1820, 1931 and 1958. In the mid-16th century the site of the grounds was occupied by a vineyard belonging to the Paluzzelli family, near Santa Maria in Domnica. That family ordered excavations there which found the coloured marbles (probably from a temple) which were re-used in Sangallo's Sala Regia at the Vatican.
