Kyrenia Castle

Kyrenia Castle stands at the eastern end of the town's natural horseshoe harbour, its medieval walls descending almost directly to the waterfront and the towers rising above the sea on three sides. The castle and the harbour are visually inseparable — the fortress was built to protect exactly this pocket of water, and the view from the ramparts down into the circular harbour basin, with fishing boats and wooden caiques moored below, is the defining image of northern Cyprus. But the castle's most remarkable content is not architectural. Inside the walls, the Shipwreck Museum houses the conserved hull of a 4th-century BC Greek merchant vessel that was discovered by a local diver in 1965 at 30 metres depth in Kyrenia harbour, making it one of the oldest seagoing vessels ever recovered anywhere in the world.

The first fortress on this site dates to the 7th century AD, built by the Byzantine authorities as a defensive response to the Arab naval raids that had begun threatening the eastern Mediterranean coastline from the mid-7th century onward. The Umayyad caliphate's expansion into the Levant and Egypt had established Arab naval capability in waters previously controlled by Byzantium, and Cyprus — centrally positioned in the eastern Mediterranean and wealthy enough to be worth raiding — was repeatedly targeted. The Byzantine castle at Kyrenia was one of the coastal installations built to provide early warning and resistance against these raids.

The fortress's first appearance in detailed written history comes in 1191, when Richard I of England — the Lionheart — stopped at Cyprus en route to the Third Crusade. Isaac Komnenos, a Byzantine aristocrat who had declared himself independent ruler of Cyprus (the Byzantine government in Constantinople had lost effective control of the island), made the mistake of seizing English shipwreck survivors and refusing to release them. Richard's response was swift: he invaded Cyprus with his fleet, defeated Isaac in battle, and captured the island's fortifications including Kyrenia Castle within a matter of weeks. Richard subsequently sold Cyprus to the Knights Templar and then to Guy de Lusignan, the former king of Jerusalem — initiating the Lusignan dynasty's three centuries of rule over Cyprus.

Under the Lusignans, the castle was strengthened and the Byzantine Chapel of St. George was built within the walls — the 12th-century chapel that still stands inside the fortress today, one of the oldest surviving structures in the complex. The Lusignan kings of Cyprus used Kyrenia as a secondary residence and as a place of refuge: several members of the dynasty died in the castle or used it as a shelter during internal succession crises.

Venetian rule of Cyprus began in 1489, when the last Lusignan queen, Catherine Cornaro, ceded the island to Venice. The Venetians immediately began a systematic reassessment of Cyprus's military installations — the standard process they applied to every significant new possession, evaluating the existing fortifications against the requirements of 16th-century gunpowder-era warfare. At Kyrenia, the conclusion was that the existing Lusignan walls needed to be thickened substantially to absorb cannon fire, and that cannon embrasures needed to be cut at strategic positions to allow the defenders to mount effective artillery. The major Venetian remodel of approximately 1540 produced the fortress largely as it appears today — the thickened walls, the modified round towers, and the cannon embrasures defining a structure adapted for the artillery age while preserving the earlier fabric inside.

The Ottomans took Cyprus in 1570–71, after a campaign that began with the capture of Nicosia and ended with the fall of the Venetian garrison at Famagusta. Kyrenia surrendered without significant resistance. Under Ottoman administration, the castle continued as a military installation before gradually transitioning to civilian use — as a prison at various periods, and eventually as a monument.

The Shipwreck Museum, installed inside the castle walls, was established after the 1965 discovery. The ship itself — a trading vessel approximately 14 metres long, built with a lead-sheathed hull to protect against wood-boring organisms — was excavated between 1967 and 1969 by a team from the University of Pennsylvania. Dendrochronological analysis of the hull timbers dated the ship's construction to approximately 389 BC; residue and tissue analysis found that the ship was already approximately 80 years old when it sank around 300 BC. The cargo — 29 wine amphorae (mostly from Rhodes), approximately 10,000 almonds, four sets of wooden cups and plates suggesting a crew of four, and millstones from Kos and Rhodes — tells a specific story of a small trading vessel working the eastern Aegean and eastern Mediterranean routes in the late 4th century BC. The conserved hull is displayed in the purpose-built museum room with the amphorae and other cargo objects arranged around it.

For the broader Cyprus context on this site: [St. Hilarion Castle](/castles/cyprus/st-hilarion-castle), in the Kyrenia Mountains above the town, is a Crusader mountain fortress reached by the same GYG tour (t457782); the two castles are within 20 minutes of each other and can comfortably be combined in a half-day.
