Il territorio di Trebbio è una meravigliosa anticamera dei Monti Sibillini: dilaga tra le colline che separano la valle del Fiastrone da quella del Chienti, prima di lambire il lago artificiale. Il Castrum Flastae, che risale all’XI secolo, comprendeva una chiesa e proteggeva numerose abitazioni. Su questo sito, tra il XIII e il XIV secolo i Magalotti costruirono un castello.
The territory of Trebbio is a marvellous ante-room to the Sibillini mountains: it spreads out over the hills that separate the valley of the Fiastrone from the Chienti river valley, before reaching the artificial lake. The Castrum Flastae, dating back to 1100, used to have a church and protected many houses. On this site, between the XIII and XIV Century, the Malagottis built a castle, subsequently a residence of the Chief magistrate and seat of the Council of Nine. The latter, flanked by the council known as ‘Fourty-eight’, which consisted of representatives of all the territory’s districts, regulated civil and political life in the castrum. It did this on the basis of the Statute, a document that contained legal and administrative directions concerning the ‘brevi’, that is to say the 4 zones in which the municipality was divided. The Statute regulated daily life in all its aspects, from the simplest to the most important, and didn’t fail to establish monetary fines that were to be paid in case of a guilty verdict.
