Until recently, it was assumed that the origins of Villa Sant'Angelo dated back to the Middle Ages, however archaeological excavations have revealed the presence of buildings dating from Roman times.Ancient walls and portions of a necropolis (including tombs, terracotta and 4th Century bronze and silver coins) have been discovered in a series of digs conducted between 1986 and 2005.In the early 20th century, numerous residents of Villa Sant'Angelo emigrated to the United States, beginning the decline of population from the peak of 1,027 recorded in the 1921 census.
