Skiathos | Greece

Skiathos is the most developed island of the Northern Sporades, known for its dense pine forests and over 60 sandy beaches. It is geographically defined by a rugged, wild northern coastline and a more sheltered, resort-heavy southern coast.

Historical Timeline

Inhabited since prehistoric times, Skiathos was settled by Pelasgians and later Ionians. In the 13th century, the Venetian Bourtzi fortress was built to protect against piracy. During the Ottoman era, the population moved to the naturally fortified Kastro on the northern tip. A critical moment in modern Greek history occurred at the Monastery of the Annunciation (Evangelistria) in 1807, where the first modern Greek flag (a white cross on a blue background) was designed and raised. The island was officially incorporated into Greece in 1830.

Demographics & Population

As of 2026, the permanent population of the municipality is approximately 5,900. The majority live in Skiathos Town (Hora). During the peak summer season, the island's temporary population can exceed 50,000. The median age of residents is 42.1 years.

Facts & Legends

Legend says the name "Skiathos" means "the shadow of Athos," as the island lies in the shadow of Mount Athos to the north. A verified technical fact: Because of the short runway at JSI, many heavy aircraft must take off with limited fuel and stop at nearby airports (like Thessaloniki) to refuel for long-haul flights.
