Palazzo Pamphilj (or del Collegio Nazareno) is a historical palace in the city of Albano Laziale, in the province of Rome, in the Roman Castles area.

It is currently a private property and is in total disrepair and neglect, despite being cited as an illustrative example of a patrician building in the Alban Hills and an 18th-century reconstruction site in a detailed study by Marco Silvestri and Enzo D'Ambrosio for the Accademia degli Incolti in 1988.

[3] As early as 1282, Cardinal Giacomo Savelli, since 1285 Pope Honorius IV, had built the abbey complex of St. Paul's,[4][5] endowing it with substantial properties in the Albanese territory and around Lake Albano (such as the picturesque hermitage of Sant'Angelo in Lacu).

[6] The trident of roads was articulated as an urbanistic expansion of the city, hitherto restricted horizontally along the route of the decayed Via Appia Antica,[7] which grafted onto today's Corso Alcide de Gasperi and developed with three roads that connected the strategic points of the city to the Abbey of St. Paul: the current Via Leonardo Murialdo (the "third street" of the Gregorian cadastre) with the cathedral basilica of San Pancrazio,[4] the current Via San Gaspare del Bufalo (the "second street" of the Gregorian cadastre) with the shrine of Santa Maria della Rotonda,[4] and the current Via Aurelio Saffi (the "first street" of the Gregorian cadastre) with the Via Appia and, slightly wrong-footing it, with Palazzo Savelli.

Next to this palace, built at the corner of the square and today's Via Murialdo and Via San Gaspare del Bufalo, on the downstream side rose the country house of the Bottini marquises.

[10] The Maculani casino, a two-story building with a courtyard, chapel, stable and dining room, was in a very bad state, unfinished and far too rustic, with the putlog holes still visible.

[14] Eventually Prince Doria Landi Pamphilj came to an agreement with the Colonna heirs, leaving to them the ownership of the Albanian palace,[15] which was ultimately sold in 1764 to the Piarist fathers of the Nazarene College in Rome[16] for 7000 pontifical scudi.

[15] Since 1758, the students of the Collegio Nazareno, the historic Roman college founded in 1630 and run by the Piarist Fathers,[17] who could not return home during their vacations, stayed at the palace in Albano.

The rector of the college, Father Bandini, thought it best to purchase the palace and the adjacent Nuñez casino instead of paying the Colonna family the rent of 200 pontifical scudi.

[12] New changes were made between 1796 and 1806 by architect Girolamo Masi, with the construction of new toilets in the palace courtyard, the closing of the gateway on Via San Gaspare del Bufalo, and the rebuilding of the dilapidated attics.

[25] After the breakthrough of the Hitler Line, the extreme defensive bulwark created by the Germans between Lanuvio, Velletri and Valmontone, on Mount Artemisio on the night of June 3-4, 1944,[26] all the Roman Castles were quickly occupied by the Anglo-Americans.

At the end of the five-month period, in the absence of other solutions, the Piarists granted permission to the evacuees to stay in the palace upon payment of a rent:[27] the structure underwent numerous tampering, so much so that it was spoken of real "violence" suffered by the building.

"[30] On March 10, 2017, the fate of the building was the subject of a conference organized by the Albano Centro Neighborhood Committee at the Saletta Vespignani adjacent to the Civic Museum, with the intervention of various political and cultural figures.

The two scholars, reading the very detailed "construction diaries" from 1777 to 1900 preserved in the archives of the Nazarene College in Rome, brought to light the whole "noisy panorama of men intent on working artfully, according to ancient techniques,"[35] where "there hovered a deep sense of humanity now unusual to us.
