The settlement took its Hungarian name from the church of St. Nicholas (Szentmiklós). Its history can be traced to the 13th century. King Béla IV presented the area to his son-in-law, Rostislav Mikhailovich, in 1247. It changed hands many times in the 14th century.
Péter Perényi, who owned Szentmiklós in the early 15th century, commenced building a castle. It suffered serious damage at the hands of Jerzy Sebastian Lubomirski's forces in 1657. The surviving edifice is the upshot of Francis I Rákóczi's rebuilding campaign.
The Schönborn era continued in Chynadiiovo well into the 20th century. The Mukachevo-Chynadiiovo estate was one of the largest in Eastern Europe. As of 1731, the estate comprised 200 villages and 4 towns, covering an area of some 2,400 km2.[1]
The town's most striking landmark is the hunting lodge of the Schönborns, the Beregvar Hunting Lodge, originally built of timber, but rebuilt as a large country residence to a fanciful revivalist design in the 1890s.
Until 26 January 2024, Chynadiiovo was designated urban-type settlement. On this day, a new law entered into force which abolished this status, and Chynadiiovo became a rural settlement.[2]
