Karystos
Karystos () or Carystus is a small coastal town on the Greek island of Euboea. It has about 5,000 inhabitants (12,000 in the municipality). It lies 129 km south of Chalkis. From Athens it is accessible by ferry via Marmari from the port of Rafina. After the Greek war of independence, its urban plan was laid out by the renowned Bavarian civil engineer Bierbach, in the middle of the 19th century. History. Karystos apparently remained inhabited throughout the early Middle Ages. As part of the theme of Hellas, it was also seat of a bishop – a suffragan of Athens – at  least since the reign of Leo VI the Wise (r. 886–912). It was among the towns listed in the 1198 "chrysobull" of Alexios III Angelos, where the Venetians were permitted to establish trade stations. In 1205 it was captured, as with the rest of the island, by James II of Avesnes, and soon it became the seat of the southern third (triarchy) of Euboea under Ravano dalle Carceri. It is likely that it was at this time, with the construction of the castle of Castel Rosso (some 4 km from the modern town, at the modern village of Myloi) and  the rise of piracy, that the town was moved from its coastal location to the inland around Castel Rosso. The town remained an episcopal see under Latin rule, with the Greek bishop remaining in office; in 1222 however it was merged with the Bishopric of Euripos (Chalcis). In 1276/7 it was reconquered by the Byzantines under Licario and held until 1296, when it was recovered by Boniface of Verona. In 1318 it passed into Catalan hands as part of the dowry of Marulla of Verona for her marriage with Alfonso Fadrique. The town was coveted by the Venetians, who already  in 1339 offered to purchase it; negotiations dragged on until 1365, however, and only in 1366 did Karystos finally pass into Venetian control when Boniface Fadrique sold the barony to the Republic. After the conquest of Euboea by the Ottoman Empire in 1470, the local Orthodox see was reactivated as part of the Metropolis of Euripos. Municipality. The municipality Karystos was formed at the 2011 local government reform, as part of the Kallikratis Plan, by the merger of the following 4 former municipalities, that became municipal units: The municipality has an area of 674.635 km, the municipal unit 166.950 km
