What is Fondi known for?

Caetani fortress built in 1319 in the center of town, a rare medieval Italian castle on flat ground rather than a hilltop. The 1378 conclave that elected the antipope Clement VII met in the Fondi cathedral, splitting the papacy for forty years. Mercato Ortofrutticolo di Fondi, the largest fruit and vegetable wholesale market in Europe by volume.

When is the best time to visit Fondi?

May–Sep. May through September is when the plain works best for visitors: the lake, the sea, and the centro storico all reachable in a single day, evenings warm enough for late dinners on the piazzas. July and August push past thirty-two degrees and the plain has no relief from heat until the sea breeze comes in. April, October and early November are dry and quiet, the citrus groves heavy, the wholesale market running at full pace. December through February stays mild compared to inland Lazio but many beach services close. The castle, the cathedral, and the Jewish quarter are walking-distance from each other in any season.

Fondi is a comune in the province of Latina, Lazio region of Italy, about 60 kilometers from Latina.

Why come

Fondi sits in the middle of its own plain, the Piana di Fondi, a fertile basin between the Ausoni and Aurunci mountains halfway between Rome and Naples, with the Tyrrhenian only a few kilometers south. The Via Appia ran straight through it. The town has been here since 338 BC, when its inhabitants gained limited Roman citizenship after the Latin War.

In 1319 Onorato I Caetani began the Castello Baronale on a stretch of old Roman walls in the center of town: round towers more than thirty meters high, one of the rare medieval Italian castles built on flat ground because the plain itself was defensible. In 1378 the conclave that elected the antipope Clement VII met here, opening the Western Schism. Giulia Gonzaga held court at Fondi between 1526 and 1534. The Mercato Ortofrutticolo di Fondi (MOF) is now the largest fruit and vegetable market in Europe, moving millions of tons of produce a year from the surrounding fields.
