Palazzo Doria Pamphilj is a monumental palace in the town of Valmontone in the province of Rome. It rises in the highest part of the city of Valmontone, almost completely razed to the ground by bombing and later rebuilt with criteria that have completely distorted its original structure. The displaced people who lost their homes during the war settled in the palace and remained there until about the mid-1970s. The Palazzo dei Conti Doria Pamphilj was built between 1654 and 1670 by the Jesuit Benedetto Molli then completed by Antonio del Grande on the pre-existing structures of the ancient Sforza castle. Inside, on the main floor there is an important cycle of frescoes, now recovered from a recent restoration, in which the most famous painters of the seventeenth century worked there: from Pier Francesco Mola who was initially entrusted with the construction site, to Mattia Preti, by Gaspard Dughet to Giambattista Tassi, from Borgognone, to Francesco Cozza. True masterpiece of the pictorial cycle is the Room of the Air frescoed by Mattia Preti which in the illusionistic breakthrough of the wall, allows the figures to move freely in the space around the Air, placed inside a golden crown supported by the four winds.
