The municipality of Tre Ville was established on 1 January 2016 when the municipalities of Ragoli, Preore and Montagne were merged.
This village lies at the feet of Monte Àmolo (1,332 m). Its main economic activities include trout farming, metalworking and woodworking. Although the etymology of the name Preore is uncertain, it is thought to derive from the Latin terms prae, meaning before, and ore, meaning mouth, opening or entrance. In other words, this is the place "before the opening", in front of "Scaléta" or Passo del Durone.
It has a noteworthy history as the most important settlement in the valley during the 15th century, under its ancient name of Mondrone. It was the seat of the Vicar of the Prince-Bishop for Giudicarie, and the seat of the court which was later transferred to Tione. The community of Preore was then made up of the present-day municipalities of Preore, Ragoli and Montagne.
Preore was the birthplace of Professor Filippo Serafini (1831-1897), a renowned student of Roman law who taught at the Universities of Pavia, Bologna, Rome and Pisa and was a senator of the Kingdom of Italy. He was the author of many legal texts, and two plaques on the house where he was born stand testament to his life’s work.
