folk art. The Museo della Civiltà dell' Olivo provides an educational look at the olive industry, from the planting of the olive through its processing into oil; the Trevi Flash Art Museum (Now Museum of Palazzo Lucarini) houses contemporary art exhibitions. Economy The mainstays of Trevi's economy are olive oil and tourism. The comuni of Trevi and Spoleto are known for the quality of their oil, a result of near-ideal calcareous soil with excellent drainage, just the right altitude for the cultivation of olive trees, and favourable climatic conditions on the west-facing lower slopes of the Apennine mountain range. Trevi's good train and highway access has made the town the most convenient base for visiting central Umbria for those who rely on public transportation; the unusual number of good restaurants in the comune is partly the cause, partly the result of increased tourism. Trevi also has some light industry and food processing other than olive oil. Holidays and local events The patron saint of Trevi is St. Emiliano; his feast is celebrated on January 27 with a night-time procession of the Illuminata, in which his statue is carried out of the Duomo around the city along the line of the earliest medieval walls. Shrove Tuesday sees a public celebration in the main piazza, and August a 3‑week-long music festival; but the main annual festivals take place in October: the Palio on the first Sunday, the Celery and Sausage Fair (Sagra del Sedano Nero e della Salsiccia) on the third Sunday, and a historical pageant on the fourth Sunday.
