On the mainland side of the hill Kanithos the castle of Karababa dominates along with the bridge of Euripus; there a unique phenomenon occurs—every six hours the direction of the water changes. Chalkida has several important landmarks. First, the new spectacular Cable Bridge, a modern technological achievement, which makes it easier to approach the city and avoid traffic congestion in downtown.

The Old Bridge Mobile, built in 1962, is used by visitors as an observation point of the tidal alternating water motion. There are also archaeological and folklore museums. The City Hall is housed in the Palace of Kochi and overlooks the beach with its beautiful architecture and wonderful balance of tumors. The Archaeological Museum contains finds from excavations in various parts of Evia, and especially Eretria.

The Folk Museum includes rare items, weapons, coins, traditional clothing, and so forth. In the center of the district lies the medieval Castle Church of Agia Paraskevi. It is a Byzantine temple rebuilt by the Venetians in the 14th century named after the patron saint of the city celebrated every year from July 26 until August 2. Other attractions are the Fort Veli-Baba, the Tower of Kara-Baba, the medieval aqueduct and the Marble Fountain.
