 The most famous of the family was Ermanno di Corrado of the Cervara branch, who between 1334 and his death in 1337 was the absolute Signore of Orvieto, where he suppressed civic liberties but demonstrated diplomatic and organizational finesse.At his death, however, the family's internecine quarrels broke the civic peace; the Monaldeschi ruptured along four lines each identified by their "stemma" or heraldic charge, the Monaldeschi della Cervara, Monaldeschi del Cane, Monaldeschi della Vipera and the Monaldeschi dell’Aquila.Angelo Monaldeschi della Vipera built the Castello della Sala on a rocky promontory about 18 km from Orvieto, not far from the border with Tuscany.
