Osa is a small hamlet of Orvieto (TR, Umbria), located at 310 m above sea level. It has only four residents, mostly in pre-1919 buildings. It is known for its 19th-century village dominated by Palazzo Netti, built by Professor Smerrini of Florence and inhabited by engineer Aldobrando Netti (died 1925), a pioneer of electricity in Umbria with works such as the Sugano power plant and the lighting of the Mancinelli Theatre, characterised by monochrome frescoes on scientific virtues (Work, Science, Water, Earth, Fire, Energy). Netti is a candidate for the FAI (Italian National Trust) Places of the Heart.
