The extremely vast area allows the construction of a grand building, comparable only to that of Doria-Pamphilj in Fassolo, while the steep slope of the terrain offers architects Domenico and Giovanni Ponzello the opportunity to experiment with an innovative architectural solution whereby the sequence of atrium-courtyard-staircase creates a wonderful play of perspectives.
Purchased by Gio Andrea Doria for his son Carlo, Duke of Tursi, it was completed in 1596 by Carlone and Orsolino with the addition of two side loggias that scenographically integrate it with the surrounding green spaces.
Owned by the Doria family until the early nineteenth century, it was enriched by the adjacent Palazzo delle Torrette (1716) and, becoming the residence of the Savoys (1819), by an elaborate internal decorative scheme of stuccoes and frescoes.
The demolition of St. Francis allowed the expansion in the back with the construction of the clock tower and the creation of a “romantic” garden that scenographically recovers the structural and decorative elements of the church.
Transformed into a college (1838) and since 1848 the seat of the Municipality, after the northern expansion of the municipal offices designed by Albini-Helg (1952-59), it is today part of the larger “Museum System of Strada Nuova“.
