Gaeta is a city and comune in the province of Latina, in Lazio, central Italy. Set on a promontory stretching towards the Gulf of Gaeta, it is 120 km from Rome and 80 km from Naples. The town has played a conspicuous part in military history: its fortifications date back to Roman times, and it has several traces of the period, including the first-century mausoleum of the Roman general Lucius Munatius Plancus at the top of the Montagna Spaccata ("Split Mountain").
