St. John Island (Agios Ioannis) is a rare 750-acre sanctuary representing one of the largest and most strategically significant private islands available in the Mediterranean. Unlike the rugged, steep topography common to many Greek islands, St. John offers approximately 300 acres of exceptionally rare flat, buildable land. Currently untouched and home only to a small herd of goats, the island serves as a monumental "blank canvas" for a world-class luxury resort, an ultra-exclusive residential community, or a private estate of unprecedented scale.
Property Details
The island is offered as an expansive, undeveloped landholding with high topographical utility.
Topography: The island’s defining feature is the 300-acre plateau of flat land, providing a stable and efficient foundation for large-scale construction that is typically unavailable in the region.
Development Potential: The massive 750-acre footprint supports diverse master plans, from a 5-star hotel complex with an integrated golf course to a high-security sovereign family compound.
Natural State: The island has remained raw and unscripted, preserving its authentic Peloponnesian character and ancient greenery.
Land & Waterfront
St. John Island is encircled by vibrant blue waters and provides panoramic views of the Saronikos and Argolic gulfs.
Shoreline: The extensive coastline offers numerous opportunities for the development of private beaches, marina facilities, and waterfront promenades.
Environment: The island provides 360-degree views of the drifting sailboats of the Saronic Gulf and the picturesque mainland mountains.
Activities: The surrounding waters are a haven for snorkeling, diving, and deep-water yachting, with the island’s scale allowing for miles of private nature and hiking trails.
Access & Utilities
Logistics at St. John Island are optimized for elite international connectivity while maintaining total offshore seclusion.
Transit: The island is a 15-minute boat ride from the fishing village of Korfos and 45 minutes by boat from Athens. By road, the trip from Athens to the nearby mainland takes approximately two hours.
Regional Infrastructure: The nearby town of Megara (30 minutes) and the village of Korfos provide essential shops, tavernas, and maritime services.
Utilities: As a 2026 non-developed asset, the island is ideally suited for the implementation of a modern, eco-friendly solar grid and advanced desalination systems, consistent with current EU sustainable development standards.
Lifestyle & Value
Offered with "Price Upon Request," St. John Island is a definitive trophy asset in a global market where 750-acre coastal holdings near major capitals are nearly non-existent. Its proximity to Athens ensures that international airports and urban amenities are consistently within reach, yet its scale provides absolute autonomy. Ownership offers the opportunity to shape a landmark residential or hospitality project in a region favored by Europe’s elite. This is a legacy investment in the heart of Greece’s most storied waters, combining ancient beauty with 21st-century development utility.
