1. Isola Santa Cristina (€24,000,000)
- Location: Northern Venice Lagoon, between Torcello and Burano, Veneto
- Size: 72 acres
- Description: Around 20 min by private boat from Venice and approximately 35 min from Venice Marco Polo Airport
- Ownership: Freehold
- Development: Developed
- Map: See on Google Earth
Isola Santa Cristina is a remarkable 29-hectare private island in the northern Venice Lagoon, located between Torcello and Burano. Part of the historic Ammiana archipelago, it is regarded as one of the last surviving garden islands in this unique lagoon landscape and is being offered for sale for the first time in more than four decades.
Owned by the Swarovski family since 1986, the island is far more than a historic property. It functions as a complete private estate, featuring a four-storey main villa, a separate farmhouse, a chapel, a heated saltwater swimming pool, boathouse, private moorings, and a helipad. The grounds also include a working vineyard producing the estate’s own Ammiana wine, together with olive groves, orchards, and traditional fish-farming valli that continue centuries-old Venetian practices.
Despite lying only around 20 minutes by private boat from central Venice and roughly 35 minutes from Marco Polo Airport, the island offers an exceptional sense of privacy rarely found so close to one of the world’s most visited cities.
As part of the UNESCO-listed Venice Lagoon, future alterations are subject to approval by the Italian Soprintendenza heritage authorities. However, the estate is already exceptionally well established, making it one of the most complete and prestigious private island properties currently available in Italy.
2. Santa Maria Island (€15,000,000)
- Location: Stagnone Lagoon, Tyrrhenian Sea, Sicily, Southern Italy
- Size: ~28 acres, ~11 hectares
- Description: ~20-minutes by motorboat from Birgi, 450km south of Rome
- Ownership: Freehold
- Development: Developed
- Map: See on Google Earth
Santa Maria Island commands a premiere location at the heart of the Stagnone Lagoon, a sheltered expanse of mirror-flat coastal water on the west coast of Sicily. In recent years, the lagoon has become recognised as one of the best places in the world for kitesurfing – an added perk for any sports-inclined investors.
The island has a mansion (460 square metres) and a 16th-century chapel. An additional residence for Santa Maria’s caretakers features alongside an animal shelter. Electricity is supplied to all facilities by an onsite generator.
While a functional olive grove is Santa Maria’s defining natural feature, the island is also populated by pine and palm trees. Prickly pears are a common sight too.
Santa Maria’s combination of natural beauty, location, and established mansion development makes it a premium opportunity for investors.
3. Isola degli Orbi (€3,000,000)
- Location: Grado Lagoon, Friuli-Venezia Giulia
- Size: 8.72 acres
- Description: Around 3–5 min by boat northwest of Grado port and approximately 45–50 km west of Trieste
- Ownership: Freehold
- Development: Developed
- Map: See on Google Earth
Isola degli Orbi is a beautifully restored 3.53-hectare private island in the Grado Lagoon, just a short three to five-minute boat ride from the historic centre of Grado on Italy’s northern Adriatic coast. Often described as the “Pearl of the Grado Lagoon,” it combines authentic local heritage with complete privacy in one of Italy’s most distinctive coastal landscapes.
The island recently underwent a remarkable transformation after being purchased through a 2025 bankruptcy auction and comprehensively restored. Today it offers a turnkey off-grid retreat featuring three traditional casoni (lagoon cottages), an artesian well, solar-powered systems, a private dock, a small gazebo island, and an 800-metre perimeter walkway surrounding an internal fishing valley. The result is a property that preserves the character of the historic lagoon while providing comfortable modern use.
Located roughly 45–50 km west of Trieste and close to the Slovenian border, the Grado Lagoon remains far quieter than many of Italy’s better-known coastal destinations, making it particularly attractive for buyers seeking privacy without sacrificing accessibility.
As the island lies within both the protected Grado Lagoon landscape and the Natura 2000 conservation network, future development is tightly regulated. However, with the restoration already completed, Isola degli Orbi represents a rare opportunity to acquire a ready-to-enjoy private lagoon estate with authentic Friulian character.
4. Ravaiarina Island (€3,000,000)
- Location: West of Isla Gorgo and Grado, eastern Marano Lagoon, Northern Italy
- Size: ~142 acres, ~58 hectares
- Description: 1km from Grado Port, 430km northwest of Rome
- Ownership: Freehold
- Development: Developed
- Map: See on Google Earth
Isola Ravaiarina is a property with untapped tourist potential.
The property has two defining features – a once-operational restaurant and a collection of purpose-built fish farm lagoons. A potential investor could once again harness the surrounding lagoon’s natural bounty for use in Isola Ravaiarina’s restaurant. An injection of capital is arguably the spark needed to bring the return of paying customers.
Ravaiarina benefits from a fully functioning harbour, making transport to and from the mainland viable – the port at Grado is approximately one kilometre away by boat.
The property’s unique features and pre-established facilities make it one of the more intriguing private islands for sale on the Italian market.
5. Isolo delle Femmine Island (€1,650,000)
- Location: West of Mondello, Tyrrhenian Sea, Palermo, Sicily
- Size: ~34 acres, ~14 hectares
- Description: ~400m from shore, 16km from Palermo Airport, 410km south of Rome
- Ownership: Freehold
- Development: Development potential (restoration of ruins)
- Map: See on Google Earth
Isola delle Femmine (Island of the Women), also known as Isolotto, is another Italian island steeped in history – from the provenance of its name to the relics it features.
One legend tells that Turkish maidens were sent from their homeland on ships and left adrift in the middle of the sea. In time, the ships came to wreck on a small island, and it was there that they lived for seven years. The island in question became known as Isola delle Femmine.
A derelict watchtower is the island’s centrepiece – a remnant of the 16th-century defence system that protected Sicily from the attacks of Corsair ships. Whilst currently in ruin, there is potential for conservative restoration – a process that could pave way for a private residence or archaeological museum. Genuine intent to rebuild the structure would require cooperation with local and national bodies. There is also a possibility to obtain funding from the European Union or the Ministries of Cultural Heritage, Activities, and Tourism for a cultural development program on the isle. Though further details on such a proposition would have to be gleaned.
As is, the island could also serve as a valuable preservation piece.
Isola delle Femmine also benefits from its premium location on the Sicilian coast – the city of Palermo, and its airports, are less than 20 kilometres away.
6. Ottagono San Pietro (€1,500,000)
- Location: Southern Venice Lagoon, off San Pietro in Volta, Pellestrina, Veneto
- Size: 0.82 acres
- Description: Around 15 min by private boat or water taxi from Venice
- Ownership: Freehold
- Development: Undeveloped
- Map: See on Google Earth
Ottagono San Pietro is one of the five historic octagonal fort islands constructed in the southern Venice Lagoon. Located just off San Pietro in Volta at the northern tip of Pellestrina, this distinctive man-made island occupies approximately one-third of a hectare and represents one of the most unusual private island opportunities currently available in Italy.
Unlike many Venetian heritage islands that already contain restored buildings, Ottagono San Pietro remains largely undeveloped, offering buyers the opportunity to shape the property according to an approved vision. The current owners have commissioned a conceptual residential project featuring a modern villa of approximately 500 m², together with a swimming pool, private boat docks, landscaped gardens, and a helipad, providing a strong starting point for future redevelopment.
Despite its remarkable privacy, the island is only around 15 minutes by private boat or water taxi from Venice, making it accessible while retaining the feeling of a secluded retreat within one of the world’s most iconic lagoon environments.
As a protected historic military structure within the UNESCO-listed Venice Lagoon, any redevelopment would require approval from the Italian Soprintendenza and other planning authorities. Nevertheless, opportunities to create an entirely new private residence on a Venetian island are exceptionally rare, making Ottagono San Pietro a unique proposition for buyers seeking a historic island with long-term redevelopment potential.
7. Crevan Island (Price Upon Request)
- Location: Northern Venice Lagoon, between Sant’Erasmo, Burano and Torcello, Veneto
- Size: 2.39 acres
- Description: Around 20 min by boat from Venice and approximately 25 min from Venice Marco Polo Airport
- Ownership: Freehold
- Development: Developed
- Map: See on Google Earth
Crevan Island, also known as Isola di Crevan, is a private island in the northern Venice Lagoon centred around a beautifully restored Napoleonic-era fort. Previously marketed internationally as the “Venetian Island Fort,” the property combines military history with modern residential comfort in one of Italy’s most iconic lagoon settings.
Positioned at the mouth of the Crevan Canal between Sant’Erasmo, Burano, and Torcello, the island enjoys panoramic lagoon views while remaining only around 20 minutes by boat from Venice and approximately 25 minutes from Marco Polo Airport. The restored residence includes electricity, heating, air conditioning, an internal canal with a private water gate, two private moorings, mature gardens and orchards covering roughly 5,500 m², and a reported helipad, creating a rare turnkey island estate within easy reach of the city.
Unlike many historic Venetian islands that require extensive restoration, Crevan has already undergone a comprehensive renovation, allowing a new owner to immediately enjoy both the property’s character and modern amenities without undertaking major redevelopment.
As a protected historic fort within the UNESCO-listed Venice Lagoon, future works remain subject to heritage and conservation regulations, with preservation taking priority over expansion. Nevertheless, opportunities to acquire an entire restored Venetian island of this calibre are exceptionally rare, making Crevan one of Italy’s most distinctive private island offerings.
8. Ottagono Alberoni Island (Price Upon Request)
- Location: Venitian Lagoon, Venice, Veneto, Northern Italy
- Size: ~7 acres, ~3 hectares
- Description: 700m from shore, 10km from Venice, ~35-min by speedboat from Lido Island
- Ownership: Freehold
- Development: Developed
- Map: See on Google Earth
Ottagono Alberoni is a private, octagonal island located in the Venetian Lagoon. The property is a historical remnant of naval fortifications first built in the 1500s.
The ~7-acre plot benefits from a premier location, with Venice just a short boat ride away. Access to the island is swift and easy, making access to the subsequent facilities and services of the city equally convenient.
Its balance between connectivity and seclusion makes Ottagono Alberoni an attractive location for a private residence.
A wall surrounds the entirety of the island, and there are multiple old constructions throughout the complex – dense greenery covers the rest of Ottagono Alberon’s interior. The island’s flagship residence spans 400 square metres and contains 10 large rooms. The home’s rooftop terrace accommodates panoramic views of the island and surrounding lagoon.
9. Scoglio di Rovigliano (Price Upon Request)
- Location: Gulf of Naples, off Torre Annunziata and Castellammare di Stabia, Campania
- Size: 1.43 acres
- Description: Around 500 m offshore and approximately 30 km SE of Naples, with boat access and views toward Mount Vesuvius
- Ownership: Freehold
- Development: Undeveloped
- Map: See on Google Earth
Scoglio di Rovigliano, historically known as Petra Herculis, is a small fortress island in the Gulf of Naples, positioned around 500 m off the coast between Torre Annunziata and Castellammare di Stabia. The islet is crowned by a Spanish viceregal fortress built in 1564, together with the layered remains of earlier religious and defensive structures.
Its setting is extraordinary. The island faces Mount Vesuvius and lies within easy reach of the Bay of Naples, yet its condition and ownership make it very different from a conventional private island estate. Declared a National Monument in 1925, Rovigliano is protected as an important piece of Campanian maritime heritage.
The ownership structure is highly complex. Private rights are reportedly divided among around 23 heirs, while one section belongs to the Campania Region and is not included in any private sale. In addition, the Italian State may hold pre-emption rights over a transfer because of the island’s protected status. Any buyer would therefore need to consolidate ownership interests and complete extensive legal and heritage due diligence.
Future use would be centred on conservation rather than new development, with all works subject to strict Soprintendenza approval. Scoglio di Rovigliano is therefore best understood not as a turnkey island residence, but as a long-term restoration and heritage-preservation project for a patient buyer willing to rescue one of the Gulf of Naples’ most distinctive historic landmarks.
