Palazzo Ducale – Giove
It is a fortified palace, elegant both inside and outside, decorated with 16th century paintings by the Domenichino and the Veronese which portray mythological scenes. The Giove castle is the core of the inhabited part of the city which developed at its foot. The palace is 5 storeys high and is rich in symbology, to begin with, the 365 windows, one for every day of the year. It most probably rose up on one of the ruins of an important temple dedicated to Giove. Exceedingly rich in history, for the entire XIIIth century, the Castle was disputed between Orvieto and Todi , then it was awarded to the Lords of Baschi. In 1300 it was under the domain of, in the following order, Amelia, Narni, the Tuscan cardinal Giovanni Orsini who put it under siege and stormed it. Pope Giovanni the XII’s reaction was severe and he repossessed the Castle and imprisoned the Cardinal in Amelia. Still more: in the XVth century it fell into the hands of the Anguillara family, who were first friends of the Pope and then enemies. In 1465, Paolo II took control of the castle once more and placed it directly under the dominion of Rome. In 1503, Cesare Borgia dismantled all the defence systems of the fortress which bloomed again under the Farnese Mattei family – so we move on to the 19th and 20th centuries – to the Ricciardi and Acquarone.

Forte Cesare – Montecastrilli
A vast and valuable building complex which, through the course of centuries, has undergone continuous and profound restructuring, so as to take on the physiognomy of an aristocratic villa, the centre of a vast agricultural estate. Of the Castle, not much more than the place-name has remained, also due to the extremely bad state of conservation of the buildings, donated in 1922 by the Ciatti family to the Municipal of Amelia. Yet Forte Cesare has an exceptionally ancient history. It was built by a Roman-Byzantine settlement (still legible) and was one of the strongholds of the so-called Byzantine Corridor, which, in the early Middle Ages, linked Rome to Ravenna.

The Alviano Castle – Alviano
The Alviano Castle which dominates the village and the valley below, has a quadrangular plant animated by corner turrets. Built in the medieval period, it was transformed into Renaissance form on the wishes of Bartolomeo di Alviano, a famous mercenary leader.
Inside the castle, a museum about Mercenary Leaders has been organised.

The Dunarobba Fortress – Avigliano
At present used as a farmhouse, its architectural importance has remained intact. It presents a square base with four round corner towers, with two orders of cornices and brackets. The original core dates back to before the year 1000. A strategic garrison at 440 metres above sea level, it was disputed between Narni and Todi between the 13th and 14th centuries, with alternate fortune.

The Castle of Sismano – Avigliano
It was a castle of a certain importance in the Middle Ages. Provided with a fortified fortress, the majestic five-storey construction, with two semi-circular towers, set upon a rampart with bastions, towers above the surrounding territory, dominant with its impressive bulk. Severly damaged in 1254 by the troops of the powerful Guelph league made up of the Municipalities of Orvieto, Perugia, Spoleto, Narni and Florence against the Todi Ghibellines, the castle was at the centre of bitter disputes between the Atti and the Chiaravalle families. A trail of bloodshed began with the decapitation of the Guelph Catalano Atti in 1393 and continued for at least a century, until 1500, when Alessandro VI intervened in favour of the Atti family, who had become Lords of Todi. But bloodshed remained between the walls of the fortress: on 14th October
1575, Eleonora Atti was stabbed to death by her husband Orso II Orsini.
