Sismano stands at an elevation of 433 metres (1,421 ft) above sea level and had a population of 12 residents in the village proper and a further 71 in the surrounding countryside in 2021, according to [Istat](/source/Istat) data.[1][note 1] ## History The large fortified *[rocca](/source/Rocca_(architecture))*, with two semi-circular towers, was first built in the 11th century as part of the border defenses of Todi. By 1292 at the latest, Cardinal Benedetto Caetani (who later became [Pope Boniface VIII](/source/Pope_Boniface_VIII)) was the owner of the castle of Sismano, purchasing it for 8,500 gold [florins](/source/Florin) from the Florentine merchant Manetto Rainaldi de' Pulci. Pulci had himself bought the castle only in 1288 from the previous owners, the brothers Pietro and Rainaldo.[2] A survey conducted at Todi records 21 [hearths](/source/Hearth) in 1322.[3] In 1324 a bloody battle was fought nearby between the forces of [Todi](/source/Todi) and [Perugia](/source/Perugia), along with their respective allies from [Narni](/source/Narni), [Spoleto](/source/Spoleto) and [Florence](/source/Florence). The castle's fortifications were strengthened in 1340, during a conflict between two local noble families, the Atti and the [Chiaravalle](/source/Chiaravalle_(family)). Their feud, which intensified after the beheading of Catalano Atti in 1393, gave rise to numerous violent episodes. In 1461 Matteo di Ulisse Chiaravalle seized the castle from Giacomo and Andrea degli Atti.[4] In 1500 [Pope Alexander VI](/source/Pope_Alexander_VI) settled the long-standing dispute in favor of the Atti, lords of Todi. On 14 October 1575, Eleanora Atti was murdered there by her husband, Orso II [Orsini](/source/Orsini). The Castello di Sismano was rebuilt in 1607. In 1620, Pope [Urban VIII](/source/Urban_VIII) granted the title of *[Marchese](/source/Marchese) di Sismano* to a member of the Neri family.[5] In 1701, Sismano was a [feudal domain](/source/Luogo_baronale) of the Marquess Corsini.[6] Later, during the pontificate of [Pope Clement XII](/source/Pope_Clement_XII) (1730–1740), the fief of Sismano was erected into a [principality](/source/Principality) in favor of his nephew [Bartolomeo Corsini](https://en.wikipedia.org/w/index.php?title=Bartolomeo_Corsini_(diplomat)&action=edit&redlink=1) [[it](https://it.wikipedia.org/wiki/Bartolomeo_Corsini_(diplomatico))].[5] By 1816, Sismano belonged to Prince Don Tommaso Corsini.[6] In 1859 Sismano had a population of 422 inhabitants, forming 77 families in 76 houses.[7] IN 1975, Sismano was detached from the municipality of Montecastrilli and incorporated into the newly established municipality of Avigliano Umbro.[8] ## Geography Sismano is a hamlet located about 4 miles (6.4 km) from [Montecastrilli](/source/Montecastrilli) and approximately 10 miles (16 km) from [Todi](/source/Todi). It stands on a hill in an open and expansive position. The climate was described as very healthy and exposed to open air currents. Outside the village there are three springs.[7] ## Economy In the mid-19th century most of the landed property belonged to the [Corsini family](/source/Corsini_family), whose historic palace stands in the settlement.[7] ## Religion The parish church is dedicated to Saint Andrew, who is venerated as the patron saint; his feast is celebrated in October.[7] ## Notes 1. **[^](#cite_ref-gistat_help_2-0)** To obtain the data from the website: 1.
