Chalkis

Chalkis, also spelled Chalkida, is the main urban center of the island of Euboea in central Greece and the capital of the regional unit of Chalkida. It sits on the Euripus Strait, opposite the Greek mainland, and functions as a port, commercial hub, and administrative seat for the area.

The name Chalkis is ancient and its exact origin is uncertain. It is commonly linked to the Greek word chalkos (copper or bronze) or to a legendary founder, but explanations vary.

Geographically, the city lies at the narrowest point of the Euripus Strait and is known for the tidal currents that run through it, which have long attracted sailors and inspired local lore.

Historically, in ancient times Chalkis was a significant Ionian city on Euboea and a member of the Ionian League. It minted coins and played an active role in regional affairs, often in competition with other Hellenic polities. Through Roman, Byzantine, and Ottoman periods the area remained important, and it became part of modern Greece in the 19th century. The modern town preserves remnants of its past in fortifications and along the waterfront, where crosses between landmasses are made by bridges over the Euripus.

Economically, Chalkis serves as a port and service center for Euboea, with commerce, tourism, and light industry contributing to the local economy. The city also hosts cultural events and maintains historical sites, museums, and a scenic promenade along the harbor.

Notable landmarks include the Chalkida Archaeological Museum, the medieval fortress of Karababa, and the two bridges across the Euripus — one historic crossing and a newer bridge that connect Euboea with the Greek mainland. The waterfront area is a focal point for residents and visitors alike.
