The first mention of the castle of Cergneu dates back to 1270, when Pietro di Savorgnano (son of Corrado di Savorgnano), who came into division with his brothers, had the castle of Cergneu in its part. Five archaeological excavation campaigns were conducted from 1999 to 2006 by the Municipality of Nimis. To get there you need to take the dirt road Cergneu - Monteprato.
