If you want to see Antimachia Castle at its best, try to get there as the setting sun casts its warm glow over the battlements. While at first sight it may not look like much of a strategic vantage point – perched on a promontory just 166m high – once you’ve explored it, you’ll see why it was so important to the Knights of St. John, who built it in the 14th century to stand sentry over the strait between Kos and Nissyros as well as the entire Kardamena coastline.
