Agiassos village, the prettiest hill town on Lesbos, sits in an isolated valley amid thousands of olive trees, near the foot of Mt. Olympus, the highest peak. (In case you're confused, 19 mountains in the Mediterranean are named Olympus, almost all of them peaks sacred to the local sky god, who eventually became associated with Zeus.) Exempted from taxes by the Turks, the town thrived. The age-old charm of Agiassos can be seen in its gray stone houses, cobblestone lanes, medieval castle, and local handicrafts, particularly pottery and woodwork.
