Nagygéc, is part of the Csengersima settlement, once an independent village, which was depopulated as a result of the great flood of 1970.The village first appeared in 1280 in the name of a nobleman, probably a member of the Csák family. The 14-15th century belonged to the Csarnovoda, Csáki, Bekcs, Darai and Drágfi families. In 1476, the Becskis of Szántai also owned them and remained their owners for centuries.
In the 18th century, the Ibrányi, Luby, Nozdroviczky and Péchy families were landlords, and in the middle of the last century, Count Majláth, the Luby and Péchy families were landlords.
In the first half of the 20th century, Béla Luby and Dr. Lajos Szómjas was the largest owner. Nagygéc is very close to the Hungarian-Romanian state border. In 1970, the settlement had 706 inhabitants.The village was almost completely destroyed in the floods that occurred on May 13, in 1970.
Its reconstruction was not allowed for flood protection reasons, and movement in the area was restricted by administrative means.
According to the 1980 census, only a fraction of the population a decade earlier, 22 people, remained in the village. In 1981, the administrative independence of the settlement also ended, its territory was annexed to Csengersima. In 2011, 10 people lived in five houses in the village.
