Kalogeros

The Castle of Kalogeros is a sprawling Byzantine ruin crowning a steep, 355-metre peak above Apollonas on Naxos’s north-eastern coast. Its slopes remain so precipitous that access is still arduous, yet the position offered superb surveillance of Aegean shipping, commanding views east towards Mykonos and beyond. Likely founded in the 7th or early 8th century, it belongs to the same era as the island’s great fortress of Apaliros, and probably began as a refuge when pirate raids drove coastal inhabitants inland, perhaps building on an older stronghold. Unlike other Byzantine castles, it stayed inhabited throughout the period and saw occasional use under Venetian and early Ottoman rule, before final abandonment after the 16th century. The settlement was substantial, covering roughly 167,000 square metres across a triangular plateau, with dry-stone walls three to five metres high and up to four metres thick, reinforced by towers and two gates. The steep eastern flank needed no wall, while the better-preserved southern section, divided by a cross wall, served as the administrative core. Traces of houses, churches, warehouses and plastered cisterns survive, though the masonry in places looks hurried, as if raised under imminent threat.
