This town has just over eight thousand inhabitants, and is located in the center of the Caudina Valley, just a few kilometers away from the famous "Forche Caudine, where the Samnite people, led by the commander Ponzio Caio, defeated the Romans and humiliated them by making them pass under the "yoke", an instrument formed by three Samnite spears crossed between them.

Airola borders to the north with Moiano, Luzzano and Bucciano (hamlets of Airola until the beginning of 1800), and to the south with Arpaia, Paolisi and Forchia. It is crossed by the Carolino Aqueduct, which originates from the Fizzo Springs that feed the waterfalls of the Royal Palace of Caserta. This was the first reason why on 30 August 1754, with the Royal Decree, King Charles conferred the title of City on Airola. But also because, at that time, the territory boasted 36 churches. Currently it still boasts of 22 churches and several noble chapels. The main Church is that of S.S. Annunziata, whose facade is the work of the Vanvitelliana School, but equally important are the Convent of the Friars Minor of San Pasquale, the Sanctuary of Maria Santissima Addolorata, the Convent of San Gabriele on the charming hill of Monteoliveto, the Monastery of Regina Coeli and the Church of San Domenico.

Of great historical and architectural importance, are the remains of the Medieval Castle and the Ducal Palace, where, Bartolomeo di Capua, former Prince of Riccia, On April 2, 1754, he welcomed King Charles and Queen Amalia, his serene wife, to refresh themselves from the labours of the long journey, in one of the visits to the works of the Carolino Aqueduct. The Town Hall currently resides in the Palazzo Montevergine, while in Piazza Vincenzo Lombardi there is the War Memorial and the statue in honor of San Giorgio Martire, patron saint of the city. The statue, donated by Airolan emigrants to America, was placed as a symbol in memory of the ancient Church dedicated to the Saint, demolished due to some structural damage following the earthquake of 1980. Airola houses the first "Telephone Museum" in Campania and the second in Italy for exhibited equipment.

This Museum is located inside the former Convent of the Dominican Fathers built in 1751, which over the years has housed first a prison and then the offices of the City.
