Overview

Euboea (also spelled Evia) is a large Greek island lying close to the eastern coast of Greece. With an area of about 3,655 km² it is the second-largest island in the country after Crete. The island runs roughly parallel to the mainland and is separated from it by narrow straits, which has shaped its history, economy and transport links.

Geography and landscape

Euboea stretches along the Aegean coast opposite regions such as Boeotia and Attica. Much of its coastline faces the Aegean Sea, while its interior is a mix of mountainous ridges, forested slopes and agricultural lowlands. The island’s varied terrain supports olive groves, vineyards and pine and oak woodlands, and provides scenic beaches and rocky headlands along long, indented shores.

History and cultural significance

Human presence on Euboea dates back to prehistoric times and the island played an active role in the classical Greek world: important ancient city-states were established along its coasts and communities from Euboea took part in maritime trade and colony-founding. Over centuries the island shared in the wider currents of Greek, Byzantine and later Ottoman history and today retains archaeological sites, classical ruins and traditional settlements that reflect that layered past.

Economy, uses and tourism

The island’s economy blends agriculture, forestry and modern industry with growing tourism. Coastal towns and resorts attract domestic and foreign visitors in summer for beaches, sailing and cultural tours. Inland areas support farming—especially olives, fruit and some grazing—and there are industrial centers where energy and mineral extraction have been developed in modern times.

Administration, transport and main towns

Administratively Euboea was long recognised as one of the country’s prefectural units (prefectures) and remains an important regional unit within Greece. The principal urban centre and island capital is Chalkida, a port town located where the island is closest to the mainland. Other notable towns include Eretria, Karystos and Aliveri. Road and ferry connections plus short bridges link the island to the Greek mainland, making it readily accessible from Athens and nearby regions.

Notable features and distinctions

  • Close coastal alignment with the mainland gives Euboea a long, narrow shape and extensive shoreline.
  • The narrow strait at Chalkida is famous for strong tidal currents that reverse direction several times a day — a local maritime curiosity.
  • Rich archaeological remains and varied landscapes make Euboea a destination for both cultural tourism and outdoor activities.
