anti-French revolt still echoes today through the Festa della Radeca, the Frosinone Carnival). Contemporary age On the occasion of the journey of Pius IX in the province of Campagna and Marittima (13-20 May 1863) by train, solemn celebrations were organized, which ended with the blessing of the pope from the balcony of the Prefecture. During this visit, the pope promised extraordinary funding for the construction of an aqueduct intended to bring running water to the city by means of a hydraulic pump, an aqueduct completed and inaugurated on December 8, 1869. Frosinone witnessed in 1867 the Agro Romano Campaign for the liberation of Rome with the Nicotera Column. The clash with the Garibaldini in Monte San Giovanni Campano, on the border with the Kingdom of Italy, is noteworthy. The relics of the "Nicola Ricciotti" Carbonara Sale, patriot of Frosinone, are kept in the National Museum of Mentana. Frosinone was removed from the Papal State and officially annexed to the Kingdom of Italy on September 17, 1870, three days before Porta Pia.

After national unification, the city, which became the capital of the district of Frosinone in the province of Rome, underwent a building renovation and architectural embellishment of the town, as evidenced by the late nineteenth-century and Umbertine buildings of the current historic center. The city became the seat of the offices of the sub-prefecture and the military district; from 1863 it was served by the state railway station, to which the local railway
