The Castle of Neratzia is one of the most iconic historical landmarks on the island of Kos, Greece. Located at the entrance of Kos Town’s harbor, this imposing fortress dates back to the 14th and 15th centuries and was built by the Knights of St. John, a medieval Christian military order, as a strategic defense point against Ottoman invasions.
The castle consists of two main walls, an inner and an outer section. The inner castle was built first, around 1380, followed by the outer wall, which was constructed in the early 16th century. The two fortifications are connected by a drawbridge that crosses a now-dry moat. This moat once separated the castle from the rest of Kos, effectively making the fortress an island in itself.
The stones used to construct the castle were often taken from ancient ruins around Kos, including pieces from the Asklepion and other ancient sites. This gives the structure a unique appearance, blending different architectural and historical elements. You can see ancient Greek inscriptions and carved stones embedded into its walls.
During the medieval period, Kos was an important stronghold for the Knights of St. John, who controlled much of the Dodecanese islands. The Castle of Neratzia played a critical role in protecting Kos and the surrounding waters from pirate raids and Turkish advances. It was part of a network of fortifications built by the Knights across the region, including the larger fortifications on the nearby island of Rhodes.
Today, the Castle of Neratzia stands as a reminder of Kos’s turbulent medieval history and is a popular tourist attraction. Visitors can explore its massive stone walls, towers, and gates. Inside, you’ll find stunning views of the Aegean Sea and the coastline of Turkey. The castle’s elevated vantage points give visitors a panoramic view of Kos Town and the surrounding harbor.
The structure has a quiet, ancient atmosphere, making it an ideal place to wander, take photographs, and imagine the bustling life of medieval Kos. Informational displays are set up throughout the site, providing historical context for the castle’s construction and its importance in the region.
The Castle of Neratzia is conveniently located at the harbor of Kos Town, making it easily accessible on foot from most parts of the town. It is often visited as part of a walking tour of Kos Town, which includes other nearby attractions such as the Tree of Hippocrates and the Ancient Agora.
Whether you’re a history enthusiast or simply looking to enjoy stunning views and medieval architecture, the Castle of Neratzia is a must-see destination in Kos.

8 months agoVisiting this place during my trip to Kos was a delight. It offers fantastic photo opportunities while exploring. History enthusiasts will particularly enjoy this site. A leisurely stroll takes about an hour, or an hour and a half if you stop to take pictures. On the top of the castle provides stunning views of Kos. It's advisable to bring a drink with you, as there were no facilities inside during our visit. The remnants of damage from a past earthquake are visible. Entry was free when I went. Convenient parking is available nearby, so there's little walking required. The locals are quite welcoming. I liked it so much that I visited twice.

a year agoI would happily pay couple of euros each to come into this fine place. A combination of modern and mythological history situated in the heart of Kos, for any history buff this is an amazing walk. As said it is free with local eateries nearby on the harbour. Please explore it is safe go down the unlit tunnels and let your inner kid go wild with enjoyment. Wish for more educational aspects to it as I was explaining to many the parts of the building and how some of it was changed to incorporate the use of it during ww2

a year agoEntrance to castle and walls from outside look really very beautiful. Unfortunatelly inside is not any exhibition. Which is very sad, it would be awesome place for museumabout history of castle. You can go around castle (part of walls are closed because they are collapsing) and take pictures of beautiful views.

a year agoLots of stones. Without any historical background or a tourist guide you won't know (just like myself) what's going on, what I'm watching or why it's there. One of many attractions but I didn't really know what's what. Free entry for everyone
