Mesta is the most exquisite example of the kind of fortress-like fortification that we remark all over southern Chios’ villages, and has been preserved better than all the other Mastihohoria. The form of this village is perhaps unique in Greece. Mesta was built during the Byzantine period patterned upon a pentagonal shape, while years later the Genoese lords enhanced its fortification. The houses are built next to each other without any gaps, leaving just two gates-entrances to the interior of the village. The alleys are narrow and most of them are arched, with houses built above the arches. The entire village has been designed as a labyrinth in order to prevent pirate troupes from reaching its centre easily. The oldest monument of Mesta is Palios Taxiarchis church. It is a one-aisled basilica built in Byzantine times. In it, there are traces of frescoes, even though most of them have been coated over. The largest church is the newer church of Taxiarches, built in 1868 on the site of the old circular castle tower. Right next to it, the central traditional village square is full of taverns and cafés. Today, Mesta is a big draw for tourists, not only because of its unique architecture, but also for the area`s natural beauties. Villagers are for the most part farmers.
