Salendo da via Maqueda sul lato sinistro della strada si trova il Palazzo tardo cinquecentesco dei
Gravina, principi di Santa Flavia. Fu proprietario del Palazzo Pietro Filangeri, governatore della Compagnia dei Bianchi, fondatore e gran protettore dell'Accademia del Buon Gusto, oggi Accademia delle Scienze, Lettere ed Arti. Tuttavia come testimonia il prospetto su via del Bosco, e soprattutto il "portale dall'elegante archivolto su piedritti scolpiti in forme di mostruose arpie ", il palazzo sorse su un edificio più antico. Tra i proprietari del palazzo si ricordano anche i Gravina principi di Rammacca subentrati nella proprietà nei primi anni del secolo scorso. Si affacciano su questa strada, dopo il palazzo dei principi di Santa Flavia,
Palazzo Francavilla,( foto a fianco ) 

E' importante ricordare che per la decorazione dei saloni di questa sfortunata dimora operò Vito d'Anna, ma anche Gioacchino Martorana e Benedetto Cotardi. Nel XVIII secolo il palazzo divenne proprietà di don Salvatore Ventimiglia e Statella dei principi di Belmonte, ultimo inquisitore del Santo Uffizio, che ne fece una struttura destinata alla formazione professionale dei ragazzi meno abbienti. Per questa sua ultima funzione l'edificio è ricordato anche sotto il nome di Ospizio Ventimiliano. Ultimo edificio ubicato al centro della strada prima della biforcazione è Palazzo Fatta. Manomessa e decisamente trasformata nel tempo questa dimora quattro secoli fa era di proprietà del pretore Cola Antonio Spadafora. Sul lato destro della strada subito dopo Palazzo Bosco si trova il tardo cinquecentesco Palazzo Strozzi, oggi Oneto di San Lorenzo.
Palazzo Del Bosco is located in what once was called Via Ruga Grande del Carmine, an important artery of Palermo lined with a series of the late sixteenth century mansions and before that time. In the 16th century Via Ruga Grande del Carmine, today Via Bosco, was also called Strada degli Strozzi due to the Florentine Palazzo Don Orazio Strozzi, today called Palazzo Oneto of San Lorenzo.
Palazzo del Bosco, of the Prince of Belvedere and Pari (Peers of the Kingdom) del Regno, gave its name to the street in the 18th century, although its origins are from the late sixteenth century.
The “Del Bosco” family was started by Arrigo Ventimiglia who was renamed Arrigo del Bosco after a lucky victory against the Chiaramonte family in the “wood” (that is “bosco” in Italian language) of Salemi.
Important family that of Del Bosco: Francesco del Bosco founded Misilmeri (little town near Palermo), Vincenzo del Bosco, Francesco’s sun, received the title of Count of Vicari in 1556, Francesco del Bosco e Aragona was the first Duke of Misilmeri, and around 1650 Cesare del Bosco e Spadafora was given the title of Prince of Belvedere. The Del Bosco family membres were the owners of the building, “a magnificent house”, up to the first half of the 19th century, according to Villabianca. The subsequent owners of Palazzo del Bosco were these: in 1859 Don Giuseppe Lanza e Spinelli, Prince of Trabia, Cav. Alessandro Benso, The Princes of Trabia, once more, and then The Lima Mancuso Family. In 1939 The Province of Palermo ( today called Città Metropolitana di Palermo) managed to buy a part of the building. Severely damaged during the last world war, indeed only a mutilated facade with fragments of windows remained of the building. Today the entire building, which is owned by the Metropolitan City Administration, has been restored and houses some offices of the Body. Some frescoes of the 17th century by V.
La Barbera and the original wooden roofs can be visible on the main noble floor.

The Palaces of Via Ruga Grande, today Via Bosco
On the left side of via Maqueda, near Palazzo Comitini n.100, there is the late sixteenth-century Palace of Gravina, Princes of Santa Flavia. Pietro Filangeri was the owner of the Palace, the governor of the “Compagnia dei Bianchi” and even the founder and Great Protector of the Accademia del Buon Gusto, now Academy of Sciences, Arts and Letters. Actually, as evidenced by the prospectus on Via del Bosco, and especially “the elegant archway on abutments, carved into shapes of monstrous harpies”, the palace was built on an older building.
Among the owners of the building are to be remembered the Princes of Gravina Ramacca who took over the property in the early years of the 19th century.
On this street, after the palace of the princes of Santa Flavia, there are Palazzo Francavilla (see photo down here),

which is today owned by Città Metropolitana of Palermo, the eighteenth-century Palazzetto Oddo and Palazzetto Balestreros of the Marquis of Bongiordano.
Palazzetto Balestreros is still owned by the ancient Balestreros family that came from Spain to Sicily in the early seventeenth century. On the left side of the road, before the fork, there is also the Palace of the Marquis of Benenati di Sant'Andrea badly damaged by the bombings of the last conflict.

It is worth mentioning something about the decorations of the halls of this unfortunate residence which were by Vito D'Anna, but also by Gioacchino Martorana and Benedetto Cotardi. In the eighteenth century the Palace was owned by Don Salvatore Ventimiglia and Statella of the Princes of Belmonte, who was the last inquisitor of the Holy Office and made the Palace a structure for the professional training of the less well-to-do. For this last function the building is also remembered under the name of Ventimiliano Hospice. The last building in the centre of the road, before the fork is Palazzo Fatta.
This dwelling, which was tampered with and decidedly transformed over time, was owned by the Pretore Cola Antonio Spadafora five centuries ago. On the right side of the road immediately after Palazzo Bosco there is the late sixteenth century Palazzo Strozzi, now Palazzo Oneto of San Lorenzo.
