Ventotene: Roman History and Crystal Waters in the Pontine Archipelago

Ventotene, where history surfaces from the sea

Ventotene is a handkerchief of volcanic tufa barely three kilometres long, suspended between Lazio and Campania in the waters of the Pontine archipelago. Small, secluded, far from the mondanity of Ponza, this island concentrates two thousand years of history into a tiny space: a Roman harbour carved from tufa, an imperial villa, a Bourbon prison, and the memories of the Fascist political internment where the idea of a united Europe was born.

The sea surrounding it is among the most transparent in the Tyrrhenian, protected by the Marine Nature Reserve that also includes the nearby island of Santo Stefano, today uninhabited.

Getting there

Laziomar hydrofoils depart from Formia (approximately 1 hour 10 minutes) along with ferries (approximately 2 hours 30). In summer there are also departures from Naples Beverello and from Terracina. Frequency varies: in high season 4–5 sailings a day, in low season 1–2. Cars cannot be disembarked, but the island can be walked end to end in an hour.

The Roman Harbour

The harbour of Ventotene is one of the most astonishing and least known Roman monuments in Italy. Carved entirely from tufa in the Augustan era, it still preserves the original quays, mooring rings and warehouses. When the sea is calm and the light is right, the submerged remains of the ancient structures can be seen through the clear water.

Beside the harbour, the Roman Fishpond — a series of basins carved into the rock for fish farming — testifies to the hydraulic ingenuity of the Romans. The complex can be visited freely and at no charge.

Villa Giulia and the political internment

At the northern tip of the island, Villa Giulia is what remains of the residence Augustus built for his daughter Giulia, exiled here in 2 BC for behaviour deemed scandalous. The ruins of the villa, with its cisterns and mosaics, look out over the cliffs.

But Ventotene is also the island of political internment. During the Fascist period, hundreds of political opponents were deported here. Among them, Altiero Spinelli, Ernesto Rossi and Eugenio Colorni, who in 1941 wrote the Ventotene Manifesto, the founding document of European federalism. The Museum of Deportation tells this story through documents, photographs and testimonies.

Santo Stefano and the Bourbon prison

Less than a mile from Ventotene, the islet of Santo Stefano houses the Bourbon prison built in 1795, a circular-plan building inspired by Bentham's panopticon. Closed in 1965, it held among its inmates President Sandro Pertini and the anarchist Gaetano Bresci. The island is reachable by boat from Ventotene harbour; restoration works are ongoing and may periodically restrict access.

The sea and diving

The Marine Reserve of Ventotene and Santo Stefano protects seabeds of extraordinary richness. The most celebrated dive sites:

• Punta Pascone — tufa walls colonised by red and yellow gorgonians, with lobsters and moray eels.
• Secca dell'Archetto — a submerged pinnacle frequented by amberjacks and dentex.
• Le Sconciglie — a rocky platform ideal for snorkelling, with posidonia and starfish.

The island's diving centres offer dives for all levels. Snorkelling is also excellent from the coves reachable on foot: Cala Nave and Cala Rossano are the most accessible.

The village and its cuisine

The inhabited centre is a web of colourful alleys overlooking the harbour. The trattorias serve local fish: stuffed squid, Ventotene-style fish soup, linguine with sea cicadas. The Ventotene lentil, similar to that of Linosa, is cultivated on the island's volcanic terraces.

Hospitality is family-run: B&Bs, holiday homes and a couple of small hotels. In August places fill up quickly; book at least two months in advance.

When to go

The ideal months are May, June, September and October. In spring the island is in bloom and empty; in autumn the sea retains pleasant temperatures and the colours of sunset over the Tyrrhenian are intense. July and August are liveable but busier and windier.

What to bring

• Comfortable shoes for the coastal paths and stone stairways
• Snorkelling equipment (also available for hire locally)
• A book about the island's history to appreciate it fully
• Sun cream and a hat: natural shade is scarce
• Cash: smaller establishments don't always accept cards

The evening walk and the sunset

The evening stroll along Ventotene's seafront is a ritual shared by residents and visitors alike. As the sun drops toward the horizon, the tufa of the cliffs ignites in pink and orange, and the profile of Santo Stefano stands black against the blazing sky. The bars on the piazza serve aperitifs with a view over the Roman harbour, where the fishermen's boats bob gently in basins the Romans carved two thousand years ago.

The evening air carries the scent of myrtle and sea salt. Herring gulls glide over the harbour, and from the trattoria kitchens comes the smell of grilled fish. In this moment, as the light shifts and the silence deepens, you understand why Ventotene is not just an island with a beautiful beach. It is a place where history, landscape and daily life interweave in a way that few spots in the Mediterranean can still offer.

Ventotene is an island where every square metre tells a story. It is not a place to be consumed quickly between a swim and an aperitif, but to explore with the curiosity of someone who knows that beneath every stone of tufa lies a history two thousand years long.
