Dionisio Tower
Johannucci or Di Giovannuccio was his original surname but then, thanks to the role of primary importance that Andrea Di Giovanuccio assumed in the second half of the 14th century in Terni and on the checkerboard of free Italian municipalities, the name "De Castello" began to appear next to Johannucci. Thus, one of the most illustrious families of Terni's medieval history, the Castelli family, was born.
Putting aside the Johannucci part, as a powerful and then also a noble and wealthy family, the Castelli family built a cluster of houses with a courtyard near the church of San Lorenzo. Today it is practically the area facing a high tower, the Castelli tower, Dionisia tower which preserves only its medieval origins as it was remodelled in the 16th century.
The building next to it (that is, the Castelli residence) was destroyed by bombing. However, the houses on the right side of Via De Filis (also remodelled and renovated several times) and a building opposite the tower from which a second tower rose, remain. Of the latter, only the ruins of the base near the archway remain, which was originally an underpass and which served as an entrance to the Castelli complex. As the times suggested, it was fortified.
On the other hand, the Castelli family played a major role in a rather turbulent period for the city's history at the turn of the 15th century. They were a family of Ghibellines. At the forefront of public debate, especially with the most determined and capable of its representatives, it was Andrea Castelli who was at war with lords and captains of fortune at the service and on behalf of the Pope.
The Castelli family's fortune lasted until 1410 and with theirs, that of the Ghibellines, who lost their supremacy with the rescission of the agreement between the two most representative families, the Castelli and the Camporeali families. However, it was Braccio da Montone a few years later who put an end to the Castelli family: it was literally wiped out. It ended in tragedy, to be sure, but nothing else is known so the subsequent fate of a family that had reached maximum power remains shrouded in mystery.
