Today known as Castello Macchiaroli, its construction dates back to the 10th or 11th century.
During the thirteenth century, the lord of Teggiano Tommaso Sanseverino and the king of Naples Charles of Anjou ordered some renovations. This was followed by a reconstruction commissioned by King Ladislaus of Durazzo (1381-1414), after the expulsion of the Sanseverino family and the confiscation of their fiefdoms by the Crown.
The previous feudal lords, having once again become lords of Teggiano shortly afterwards, promoted further renovations.
Under the powerful prince of Salerno Antonello Sanseverino, the castle became one of the fulcrums of the so-called Conspiracy of the Barons against King Ferrante of Aragon, and was later involved in a harsh siege by King Frederick (1497). In the seventeenth century it was finally renovated and transformed into a palace. The complex has an elongated quadrangular layout.
The external stone wall rests on a powerful scarp base and is equipped with five circular towers, four at the corners and one at the entrance, which date back to the fifteenth century.
