Variano borders with the municipalities of Ailano, Caianello, Marzano Appio, Pietravairano, Pratella, Presenzano, Raviscanina, Riardo and Teano.

Remains found on the hills of Vairano certify that primitive men lived in caves or in wooden huts.

The Samnites built on our hills fortified cities, as we know from the remains visible on Montano, Caievola and Monteforte.

In the 11th century, the Normans subdued the Lombards, and in 1191 emperor Herny VI of Hohenstaufen gave the castle to Roffredo dell’Isola, the abbot of Montecassino.

Garibaldi and Victor Emmanuel II met in Vairano at Taverna della Catena to ratify the Unity of Italy.
