With the abandonment of Fylakopi, Dorian settlers from Laconia settled on the island, who together with the previous inhabitants built a new city further west in the current area of Klima. This new city allowed Milos to oversee the bay of the island for any pirate raids, had its port and was of course fortified by the three hills. At the same time, the inhabitants fortified it with walls that reached the sea and created large public buildings, an aqueduct, a gymnasium, a market, sanctuaries and a cemetery.
During the period the city of Klima presents intense economic and cultural development. Ceramics flourish with the famous “Apple amphorae” decorated with elements of Greek mythology, sculpture, craftsmanship, stamping on stones, goldsmithing with the wire technique, while coins were minted that originally had the apple as a symbol. Also at that time there was an increase in trade, exploitation of ores, while the local alphabet was developed, samples of which are still preserved in tombstones.
