Challenmic and euccess Chalcis

The modern town[edit]
The city hall Courthouse
Chalkida became part of the newborn Greek state after the Greek War of Independence. The modern town received an impetus in its export trade from the establishment of railway connection with Athens and its port Piraeus in 1904. In the early 20th century it was composed of two parts—the old walled town at the bridge over the Euripus, where a number of Turkish families continued to live until the late 19th century, and a sizeable Jewish community lived until World War II, and the more modern suburb that lies outside it, chiefly occupied by Greeks.^[3]
The old town, called the Castro (citadel), was surrounded by a full circuit of defense walls until they were completely razed for urban development around the start of the 20th century.^[13][14]
The city is served by a railway station and is the terminus for the Athens Suburban Railway to Athens.
Ecclesiastical history[edit]
Greek bishopric[edit]
St Demetrius church
The Byzantine diocese of Chalkis was initially a suffragan of the Archdiocese of Corinth, but in the 9th century was transferred to the Metropolitan of Athens, remaining in the sway of the Patriarchate of Constantinople. It was also known as Euripo, like it's mentioned in the Byzantine imperial Notitia Episcopatuum since emperor Leo VI the Wise (886-912).
Several of its Greek bishops are recorded, but some disputed :

• 
  Constantinus, signed in 458 a letter by the bishops of Greece to Byzantine emperor Leo I the Thracian after the murder by Coptic mobs of patriarch Proterius of Alexandria.
  
  • 
    Lequien list before him Anatolius (in 363), but he was probably bishop of Beroea in Syria Prima (now Aleppo).
    
  • 
    next Lequien inserts, by benefit of doubt, Iohannes Damasceno, whom he also lists as bishop of Euroea (in Phoenicia) alias Evaria, in Phoenicia.
    
• 
  Teodorus and Teofilattus, successive (?) bishops of Euripus, participated in the 869–70 Church council held at Constantinople.^[8] viz. the Council of Constantinople of 879–880, both treating the fate of Patriarch Photios I of Constantinople.
