The "Rassegna Internazionale del Folklore" (International Folk Festival) began in 1978 on the initiative of the town council of Castiglione del Lago and the Trasimeno Tourist Office.
Organised by the " Agilla e Trasimeno " folk group, this festival promotes cultural exchanges between folk groups. It also give the traditions and the cultures of different countries the opportunity of being known. Shows are held in a suggestive theatre created inside the medieval fortress and then performed again in other Umbrian theatres.
The International Folk Festival is well known both in Italy and abroad. Thanks to the originality and quality of its shows, this festival represents one of the most important exhibitions not only in Umbria but also in Italy.
