The Kastro (Castle) of Chios stands at the northern tip of Chios Town (Hora), overlooking the harbour and the Turkish coast just 8 km away. It is one of the most important and complete medieval fortifications in the Aegean. Originally built by the Byzantines in the 10th century, the castle was substantially rebuilt and expanded by the Genoese after they took control of Chios in 1346 and established the Mahona trading company. The Genoese ruled Chios for over two centuries until the Ottoman conquest in 1566. The castle is distinguished by its massive walls, towers, and the Porta Maggiore (Great Gate) — a monumental gateway with a portcullis. Unlike many Greek castles, the Kastro of Chios was never entirely abandoned: families still live within its walls in Ottoman-era timber-framed houses (konaki), creating a uniquely atmospheric neighbourhood. Inside the walls you will find: the Byzantine-era church of Agios Georgios (later converted to a mosque by the Ottomans and now a museum), the remains of a Genoese powder tower, small squares shaded by jasmine and bougainvillea, and a remarkable mixture of Byzantine, Genoese, Ottoman, and neoclassical architecture. The castle walls offer excellent views over the harbour, the Turkish mainland, and the island of Çeşme (İnce Burun). Best visited in the late afternoon when the light is warm and the neighbourhood comes to life.
Local Tips
Walk up from the harbour through the Porta Maggiore at dusk for the best light and atmosphere. The small square just inside the gate has excellent views and a friendly café. Look up at the carved Genoese coats of arms above doorways — they are remarkably well-preserved. The maze of lanes inside is small enough to explore fully in 45–60 minutes.

The Chios Castle neighbourhood still has families living inside. Walking through the Genoese gates at dusk is one of the most atmospheric experiences in the Aegean. The mix of Byzantine, Genoese and Ottoman layers is fascinating.
Great to explore at any time of day. I loved finding the tiny squares and carved Genoese coats of arms above doorways. The Giustiniani museum inside is small but excellent. Allow at least an hour.
