Perched on a hill, almost above the fertile land, covered with olive trees, the town is famous for the production of oil, which has a very ancient tradition. Trevi has a Roman origin and it is marked by a robust and compact plan, typical of the medieval times, enclosed by walls with a radius of 70 meters. The pavement is very particular covered by pebbles, which form traditional figures on it.
Among the principal buildings: the Church of S. Emiliano, built between the XII and XIII century and completely rebuilt in 1865. The original structure retains the three apses of the Romanesque era.
The Piaggia District that is an area where you find the church of S. Lucia, built in the fourteenth century, that of S. Chiara with an elliptical plant and the Palace of the XVI century that houses roman exhibits and frescoes of the fourteenth century.
S. Francis, a former convent, repeatedly restructured and now used as a Civic Art Gallery with works by Pinturicchio, Alunno and John of Corraduccio. For those who are interesting to spend a holiday, accommodations in Trevi are really numerous.
