The most famous noble family from the north-west of the Timiş-Torontal county in the XVIIth-XIXth centuries was the one of the Counts Nacu, Aromanians coming from Greece and settled in Banat. The Nacu brothers, Hristu and Chiril, converted to the catholic religion and they Magyarised their names, turning them into Nakó Kristóf and Cziril. They bought the land from Sânni colau at an auction in 1781. in 1864, the Count Kálmán Nakó began the building of the castle, in neoclassical style, located in the middle of a park with rare essence trees. The most important piece of the manor is the medieval tower which is the centre of the building with 99 rooms. According to the monograph of Sânnicolau Mare written by Ph.D. Prof. Ioan Romoşan, the rooms became true museum halls, housing valuable pieces: 5,000 volumes of the family library, a Cinquecento altar, paintings of the masters Lenbach and Schrottberg, a Venetian statue sculpted by Carducci, paintings by Pettenkofen, Frygies and Blaas, but also by the Count Kálmán Nakó’s wife, Berta; a copy of the famous treasure from Sânnicolau Mare, sculpted and engraved Flemish cupboards, rare porcelains, a jewellery box which contained original letters received from the composers Franz Liszt and Richard Wagner or from Francisc (Ferencz) Deák, of romanian origin, called “the nation’s wise man”, whose face is printed on the most valuable hungarian bill, the 20,000 forint one. One of the rooms housed the hunting trophies of count Kálmán, brought from his first expedition to Africa. Unfortunately, the valuable items from the Counts Nakó’s castle disappeared after World War I, when Banat was, for a short time, under Serbian and French ruling. Over time, the Nakó Castle had several destinations: it was the residence of the first agricultural school from Romania, it became the legionnaire headquarters in 1941 and a weaponry storage facility. After the war, it became the residence of the school for tractor drivers and of the agricultural school (1949-1951; 1953-1955); later on, it hosted the Béla Bartók Museum, inaugurated in 1981, then it became the Pioneers’ Centre. After 1990, it was turned into a discotheque and a computer club. In the first decade of the XXIth century, it became the Cultural Centre and the Museum of the town of Sânnicolau Mare.
