Thassos is a Greek island in the North Aegean Sea. With its rich history and archaeological remains and wonderful beaches it is an island worth visiting. The mountainous villages in the inland have traditional architecture, with stone houses, paved streets and grey-tiled roofs. “Green” is usually the first adjective you’ll hear if you ask anyone that has been to Thassos what it is like. The landscape of the island is great for trekking with some interesting paths leading to abandoned places, castle ruins and caves. The most interesting sightseeing to visit in your Thassos holidays is the Ancient Agora and the Monastery of Archangel Michael.
