St. Thomas Island (Agios Thomas) is an extraordinary 300-acre sanctuary located in one of Greece’s most visually captivating regions. As the middle island in a trio within the Diapori chain, it represents a rare opportunity for large-scale development in the Saronic Gulf. The island is characterized by its lush, naturally sculpted terrain and emerald waters, offering a secluded Mediterranean environment within immediate reach of Greece’s primary economic and transit hubs. It is a premier candidate for a world-class eco-resort or a high-security residential compound.
