Situated 25km north of Serres, the remains of the medieval fort that gave the town its name ‘Iron Castle’ can still be seen in this idyllic traditional village with shady squares, stone bridges and waterfalls. The Issari Fort, built by Byzantine Emperor Basil II and 155 meters tall, is the most imposing feature of the town’s northwestern side. But there also lie the Aghios Dimitris church, carved into a rock, and the Kroussovitis river which cuts the town in two.
