There aren’t documents which tell us about the origins of Casteltodino but, the eagle todina that stands out on the door of the village, already tells of its close relationship with the nearby power turderde.

Casteltodino, between history and tradition

The first agglomeration was built–like the nearby castles of Quadrelli and Ciciliano–around one of the villas that were formed following the distributions of territories to Octavian veterans around the territory of Todi.

One tradition has it that the gens Tuditana – of which Caius Sempronius Tuditanus is the most illustrious representative – was the one who founded the fort that later became first Castel Tuditano and then Casteltodino. 

Probably it was pagus of the nearby municipality of Carsulae until it became, in the 10th century property of the Arnolfi attested by donations of land and churches to the Monastery of San Nicolò of San Gemini and the Monastery of Farfa.

Among the various vicissitudes of the time, the 1366 siege perpetrated by John the Acute was the one that affected Casteltodino the most, as well as the whole territory.

The following years saw the castle play a leading role in clashes between Guelphs and Ghibellines, and between the Atti and the Chiaravalle.

The descent of Charles VIII with the Landsknechts – at the end of the 15th century – did not spare this territory, which, however, was always supported by the Todi power that, over the years, always maintained a castellan there because of the importance of the place, a crossroads of the Petrosa road – also known as the road of the Seven Valleys – that from Todi joined there to the Amerina road and became one of the most important communication routes with Rome.
