Like other Italiannoble families, the Pamphili bought property and created self-styled principalities. Family members regularly had princely titles bestowed upon them by family patriarchs or matriarchs. Olimpia Maidalchini received the honorific title of Princess of San Martino, effectively turning the small enclave of San Martino into a principality in its own right. After he left the cardinalate to marry, Camillo Pamphili was given the titles of Prince of San Martino and Prince of Valmontone.
Between 1639 and 1649, the Pamphili fought the Wars of Castro alongside the Barberini against the Farnese dukes of Parma who controlled Castro and its surrounding territories. The conflict raged first under Barberini Pope Urban VIII and later under Pamphili Pope Innocent X. Pope Urban VIII died in 1644 only two months after a peace accord was signed between the papal families and the dukes. Pope Innocent X was elected to replace him. Innocent set about investigating some of the finances related to the conflict which had been administered by the Barberini. A number of Barberini family members were forced into exile but were later reconciled with the papacy and the Pamphili through the marriage of Maffeo Barberini and Olimpia Giustiniani, a niece of Pope Innocent X. On the orders of Innocent X, Castro was razed on 2 September 1649 by troops of the Papal Army and never rebuilt.
Family property
, by the architects Girolamo Rainaldi and Francesco Borromini, is located in the heart of Rione Parione, south of the church of Sant'Agnese in Agone in Piazza Navona, the Pamphili neighborhood of Rome, named for this reason Isola de' Pamphili. From 1652, on Saturdays and Sundays in August, the piazza was turned into a lake to celebrate the Pamphili family, a festival that was suppressed in 1866. Today, the palace functions as the Brazilian Embassy in Rome. The tomb of Innocent X is located in Sant'Agnese. In 1634 the Pamphilj bought the baronial palace in Valmontone, a town near Palestrina, outside : Camillo Pamphili was determined to create a sort of new “ideal city”, so the palace and the main church were rebuilt and decorated by important baroque artists, like the architect Mattia de Rossi, and the painters Pier Francesco Mola, Gaspard Dughet, Guglielmo Cortese, Francesco Cozza and Mattia Preti. Another building in central Rome is the Palazzo Doria Pamphilj, which houses the gallery of the same name.
