Northwest of village Armolia on top of a 220 metres hill dominates the castle of Apolichnon, built in 1440 by the Genoan Nicolo Banca Ioustiniani, which can be validated by the latin inscriptions and the blazon on the lintel of the castle's entrance. Thanks to it's dominating position, the plains of Kalamoti and Armolia villages had been opticaly controlled, but also the sea area of Komi. The castle, alongside the Viglas ( watchtowers ) cosisted as a part of the Genoese inspired defence system for Chios island, in which was applied extensive use of smoke signals during the day and fire signals during the night.
