Velletri ([velˈleːtri]; Latin Velitrae) is an Italian town of 53,298. It is a comune in the province of Rome, on the Alban Hills, in Lazio (Latium), bounded by Rocca di Papa, Lariano, Cisterna di Latina, Artena, Aprilia, Nemi, Genzano di Roma, Lanuvio.

It was an ancient city of the Volsci tribe, and its status was influential in the time of King Ancus Marcius, enough to be on a par with Rome, and the family (gens) Octavia, to which the first Roman Emperor Caesar Augustus belonged, came from Velitrae, and the future emperor spent his youth there.

Since then, it was been the site of two historical battles in 1744 and 1849. In the Middle Ages it was one of the few “free cities” in Lazio and central Italy.

Velletri is a wonderful location from which to see central Italy. Less than 35 km from Rome to the north and the seaside town of Nettuno to the west, it is also less than two hours’ drive from Naples. Nestled in the Parco Regionale dei Castelli Romani, there is an abundance of hiking and cycling in the area, and it a stone’s throw from neighboring towns of Ariccia (porchetta), Nemi (wild berries) and Lariano (porcini mushrooms), as well as Castel Gandolfo, the summer home of the Pope.
