Just a short walk from the bustling harbor and central market, the Castle of Chios (also known as Kastro) stands as a silent sentinel over centuries of the island’s tumultuous and fascinating history. This impressive medieval fortress, located at the northern edge of Chios Town, offers visitors a rare glimpse into the island’s strategic importance in the Aegean Sea and its layered past under Byzantine, Genoese, and Ottoman rule.
The original foundations of the castle date back to the Byzantine era (9th century), but it was during the Genoese occupation in the 14th century that the fortress was significantly expanded and fortified. With its massive stone walls, imposing bastions, and fortified gates, the castle was designed to protect the island from pirates and foreign invaders. Later, during the Ottoman period, it served both defensive and residential functions, leaving behind architectural influences still visible today.
One of the most striking features of the castle is the main gate, known as Porta Maggiore, which leads visitors through thick walls into a self-contained community. Inside, the castle was not just a military structure but also a vibrant neighborhood where people lived, worshipped, and worked. Many original houses, cisterns, and narrow alleys still remain, creating an atmospheric setting that evokes the feel of a long-forgotten world.
Among the most notable landmarks inside the castle is the Ottoman-era mosque, now a Byzantine Museum, displaying artifacts from various historical periods of Chios. Another highlight is the Tomb of Kara Ali, the Ottoman admiral whose ship was blown up during the Greek War of Independence in 1822—a pivotal event in Chios’s tragic history.
Today, the Castle of Chios is a peaceful place to wander and explore. Stroll through its maze-like paths, admire the ancient masonry, and imagine life within its protective walls. The area offers beautiful views of the sea, especially at sunset, and serves as a cultural and historical landmark for both locals and visitors.
Whether you’re a history enthusiast or a casual traveler, the Castle of Chios offers a compelling blend of storytelling, architecture, and quiet charm. It is not just a monument, but a living piece of the island’s identity—well worth a visit during your stay.
