Chalkida, capital of the island of Euboea (Evia)

Chalkida (Χαλκίδα) is the capital of the island of Euboea (also called Evia). Chalkida belongs to the region of Central Greece and lies on both sides of the narrow Euripos strait, i.e. partly on the mainland and partly on the island of Evia.

The name of the town comes from the numerous copper deposits in the area.

Since 411 BC, Chalkida has been connected to the mainland by a bridge, and in 1992 a multi-lane suspension bridge over the Euripos Canal was completed, contributing to a significant improvement in traffic. 


The Euripos (Greek Εύριπος, Évripos) is the narrowest strait in the world and is only 40 metres wide at its narrowest point. It separates the island of Euboea from the Greek mainland and divides the capital of Euboea, Chalkida, in two.

One feature of this strait is its unusual tidal currents. A distinction must be made between regular currents, which regularly change direction four times a day, and irregular currents, which change direction up to twelve times a day when the moon is waxing.


By the way, here is a live stream of the Evripos phenomenon.


The naming of Euripos goes back to a mythological incident:

Euripos, an ancient explorer who lived in Chalkida, wanted to get to the bottom of the mystery of the changing directions of the currents and drowned during one of his attempts to swim the channel at its narrowest and at the same time most dangerous point.

Another tradition reports that Aristotle threw himself into the current here out of desperation because he could not solve the riddle.

In his work "Meterologica", he too had tried in vain to clarify the strange tidal phenomenon. 

Even today, there are different views. For visitors, this phenomenon is always interesting and fascinating, whether it can be explained or not.


And here are three videos about Chalkida on Youtube:

Ancient Chalkida


Chalkida/Chalkis was probably originally a settlement of Phoenician purple fishermen. Trade flourished here early on and the peninsula of Chalkidiki, which derives its name from Chalkis, was colonised. But colonisation efforts also reached as far as Lower Italy and Sicily. 

In the 7th century BC, Chalkis fought the protracted and ultimately victorious Lelantian War against the neighbouring city of Eretria for supremacy on Euboea. 

As a fortress and trading town, Chalkis remained important during antiquity and throughout the Middle Ages. Under the Ottomans, the pasha for eastern central Greece sat here.
