In the 8th century the area is recorded as a
Lombard curtis, an organized rural estate. In 1195 a castle known as Naharco was built by
Conrad of Urslingen, imperial vicar. In the early 13th century this castle was destroyed and subsequently rebuilt by
Spoleto, at which time it was renamed ''Sant'Anatolia'' in honor of a martyr venerated by the
Benedictines. Throughout the 13th century the territory was contested between the
dukes of Spoleto, the comune of Spoleto, and the Papacy, eventually remaining under the authority of Spoleto and the Papal States. In 1332 the area came under
Ghibelline influence associated with Federico di Urbino. In 1338 several castles refused submission to Spoleto, and the dispute was brought before the ducal court at
Montefalco. The outcome was an acquittal and the recognition of full jurisdiction, together with the formation of a federation of twelve castles under the Abbey of
San Pietro in Valle. Between the 14th and 16th centuries there were ongoing territorial disputes with Caso and
Scheggino. In 1522 an uprising against Spoleto, led by the
bandits Picozzo and Petrone, was suppressed by troops of the
Orsini family; the castle was burned and the rebels were killed. In 1551 a local statute was issued, establishing a system of government based on a general council of household heads, alongside officials including a
vicario,
podestà,
camerario,
baiulo, and notary. The community remained broadly loyal to Spoleto and the Papacy until 1798. Between 1809 and 1814 the territory formed part of the rural canton of Spoleto. By 1827 it included the subordinate communities of Caso, Gavelli, Monte San Vito, and Civitella. After Italian unification there were proposals to merge the valley communities into Scheggino, but these met with opposition, particularly due to rivalry with Sant'Anatolia. In 1880 the municipality of Castel San Felice was suppressed and annexed to Sant'Anatolia. In 1895 the population amounted to 1,188 inhabitants. In 1927 the municipality was dissolved and incorporated into Spoleto under appointed administration, before municipal autonomy was restored in 1930. == Geography ==
