The Dodecanese, Greece’s hidden gems, include Rhodes & Kos along with medieval castles, sandy beaches, Italian influences & Greek charm under the Aegean sun.

The Dodecanese, a captivating archipelago in the southeastern Aegean Sea, offers a mix of medieval history, crystalline waters, and rugged landscapes. Unlike the Cyclades’ white-and-blue aesthetic, these islands boast Venetian castles, Byzantine churches, and a strong Italian influence. This guide covers their history, geography, climate, and a full list of islands.
History
Ancient & Byzantine Eras
The Dodecanese (Greek for “Twelve Islands”) have been inhabited since prehistoric times. Rhodes, the largest island and capital, was home to the Colossus of Rhodes, one of the Seven Wonders of the Ancient World. The islands later became part of the Byzantine Empire, leaving behind stunning churches and monasteries.

Knights of St. John & Ottoman Rule
In 1309, the Knights Hospitaller conquered Rhodes, building its iconic Palace of the Grand Master. The Ottomans took control in 1522, ruling until 1912.
Italian Occupation & Modern Greece
Italy seized the Dodecanese in 1912, adding Art Deco architecture (especially in Kos and Leros). After WWII, the islands finally joined Greece in 1948.

Geography
The Dodecanese lie near Turkey’s coast, with 15 major islands and over 150 smaller islets. Key features:
– Diverse landscapes: Lush Rhodes vs. arid Astypalea.
