The main nucleus of the Baronial Palace of Monteroni originated in the 14th century by the Montoroni family, feudal lords of the hamlet.

The feudal estate of Monteroni has been part of the County of Lecce since the beginning of the 12th century, founded by the Normans during the 11th century. The Counts of Lecce assigned the feudal estate of Monteroni to various trusted feudal lords. The first were the De Cremona family, who received the hamlet directly from Frederick II of Swabia around 1250. After several changes of feudal lords, the Monteroni hamlet was definitively assigned to the Monteroni family in 1291, and from then on, the hamlet became an integral part of the County of Lecce.
