Pirgi may be the most unusual of the mastic villages, but Mesta is the island's best preserved: a labyrinth of twisting vaulted streets link two-story stone-and-mortar houses that are supported by buttresses against earthquakes. The enchanted village sits inside a system of 3-foot-thick walls, and the outer row of houses also doubles as protection. In fact, the village homes were built next to each other to form a castle, reinforced with towers. Most of the narrow streets, free of cars and motorbikes, lead to blind alleys; the rest lead to the six gates. The one in the northeast retains an iron grate. Artists and craftspeople are attracted to this ancient area, so you’ll unearth art galleries and craft boutiques with a little hunting here.
