Challenmic and euccess Chalcis

Latin crusader bishopric[edit]
At the establishment of the crusader state Lordship of Negroponte, Chalcis or Negroponte (seat of the central one of its three 'triarchies' constituent baronies) became a Latin Church diocese, the first bishop being Theodorus, the Greek bishop of the see, who entered communion with the see of Rome,^[15] installed by papal legate.
On 8 February 1314, the Latin see was united in commendam (as an 'additional benefice') with the Latin Patriarchate of Constantinople, so that the exiled Patriarch, excluded from Constantinople itself since the Byzantine reconquest of the city, could have actual jurisdiction on Greek soil and exercise a direct role as head of the Latin clergy in what remained of Latin Greece.^[16]
Main sights[edit]
The church of Saint Paraskevi (the patron saint of the island) was the church of the Dominican Priory of Negroponte, one of the first two houses authorized for the Order of Preachers' Province of Greece in 1249. Started about 1250, this is among the oldest examples of early Dominican architecture surviving, and is one of the only early Dominican churches to retain its original form until the present.^[17][18] The central arch over the iconostasis and the ceiling and walls of the south chapel are the best examples of Italian Gothic stone-carving in Greece.^[19] Images of the Dominican saints, Dominic and Peter Martyr, stand at the base of the central arch.^[20] The north chapel holds the tomb of the founder of the senatorial Lippamano family of Venice. Some of the column capitals are Byzantine.
The bridges[edit]
The Chalcis' Bridge connecting the island with the mainland of Greece.
The town is now connected to the mainland Greece by two bridges, the "Sliding Bridge" in the west at the narrowest point of the Euripus Strait and a suspension bridge.
The Euripus Strait which separates the city and the island from the mainland was bridged in 411 BC with a wooden bridge. In the time of Justinian the fixed bridge was replaced with a movable structure. The Turks replaced this once again with a fixed bridge. In 1856, a wooden swing bridge was built; in 1896, an iron swing bridge, and in 1962, the existing "sliding bridge"; the construction works of the 19th century destroyed the most part of the medieval castle built across the bridge. The Euripus Bridge or Chalcis Bridge, a cable-stayed suspension bridge opened in 1993, joins Chalcis to the mainland to the south.
A special tidal phenomenon takes place in the strait, as strong tidal currents reverse direction once every six hours, creating strong currents and maelstroms.^[21][22]
Municipality[edit]
The municipality Chalcis was formed at the 2011 local government reform by the merger of Chalcis city itself with four former municipalities, which also became municipal units:^[23]

• 
  Anthidona
  
• 
  Avlida
  
• 
  Lilantia
  
• 
  Nea Artaki
  

The municipality has an area of 424.766 km², the municipal unit 30.804 km².^[24]
