San Michele Arcangelo is the Roman Catholic church in town of Montasola, in the province of Rieti, region of Lazio, Italy.
A church at the site was likely present from early medieval times, and during some decades of the 20th-century, it shared parish functions with Santi Pietro e Tommaso.
Restoration took place in the 19th century, under local patronage of persons emigrating from the town.
It is said that Cimini discovered by chance a treasure of gold in his bakery in Rome, and this allowed him to endow this oratory.
The interior is rich in polychrome marble and has a painting depicting the Holy Conception attributed to the school of Antonio Gherardi.
