Villa Mattei

The Villa Celimontana (previously known as Villa Mattei) is a villa on the Caelian Hill in Rome, best known for its gardens. Its grounds cover most of the valley between the Aventine Hill and the Caelian.

The Villa Celimontana is situated on the summit of the Celian Hill in the south-east of Rome in the Rione Celio. The principal entrance is near the Piazza della Navicella, beside the Basilica Santa Maria in Domnica. A secondary entrance is situated on the Clivo di Scauro near the Basilica Santi Giovanni e Paolo. The park is a continuation of Baths of Caracalla.

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.

In 1553 the vineyard was acquired for 1000 gold scudi by Giacomo Mattei (who also built the 15th century building in piazza Mattei), but it was Ciriaco Mattei who transformed it into a villa in 1580, instructing the architect Giacomo Del Duca (a student of Michelangelo) to build the villa and the first garden scheme. The original villa has been much adapted, but was probably a single-floor structure with a portico along its facade, topped by a Doric frieze and balustrade which still survive. It now has a quadrangular plan with two low wings and a piazza on an artificial platform supported by large ancient walls (largely Flavian and still visible from the south side).
