Fiano Romano is a town and comune (municipality) in the Metropolitan City of Rome, Italy, approximately 40 kilometres (25 mi) north of that city.
 Fiano Romano borders the following municipalities: Capena, Civitella San Paolo, Montelibretti, Montopoli di Sabina, Nazzano.
 There are multiple hypotheses about the origin of the name Fiano:
 In 1872, following a request made  by the City Council, the name officially changed in Fiano Romano through a royal decree by Victor Emmanuel II.
 The territory of Fiano Romano, due to its position close to the Tiber river, has been inhabited since the archaic ages: in fact, ceramics from the 8th century BC have been found, which show the cultural influence in the area of Faliscans, Sabines, Etruscans and Latins.
 Between the 7th and 5th centuries BC the area was under the control of the ancient city of Capena, ally of Veii: in this period was the foundation of the nearby sacred grove of Lucus Feroniae.
 At the beginning of the 4th century BC Rome completed the conquest of the entire area which passed under its control. Lucus Feroniae remained the main attraction: Hannibal, in 211 BC, went there to plunder the sanctuary, while in 70 BC many lands around the sanctuary were expropriated and awarded to the legionaries of Caesar by Antonio and  Octavian (the future Augustus). The construction of the Villa dei Volusii also dates from this period. For the whole Roman imperial period the area was very active in the production of cereals, wine and olive oil.
 In the Middle Ages the territory of Fiano passed under the control of the various religious centers and monasteries in the area (a 1081 bull of Pope Gregory VII assigns the possession of the Flaiano fund (Castellum Flaianum) to the Monastery of San Paolo fuori le mure).
 In the Renaissance period it was a fief of the Orsini, a powerful noble family, who in 1489, with Niccolò III Orsini, built the castle there. Fiano then passed to the Sforza family who made Fiano as a Duchy (bull of Pope Pius V in 1608), then to the Ludovisi-Ottoboni-Boncompagni family.
 In 1897 the last Duke of Fiano Marco Boncompagni Ludovisi Ottoboni sold the entire property to Carlo Menotti, a construction contractors, building contractor, land speculator and politician.
 After the Fascist era the lands were entrusted directly to the peasants while part of the castle was donated by Menotti family to a religious order.
 In 1993 the Municipality of Fiano Romano bought the entire Ducal Castle.
 Fiano Romano rises on the right bank of the Tiber river, which separates it from the Sabina. The territory is mostly hilly but there are large flat areas alongside the river. Average height is about 86 metres (282 ft) above sea level, with a minimum height of 17 metres (56 ft) and a maximum of 244 metres (801 ft).
 The climate is temperate with long, dry summers and generally mild but rainy winters, making Fiano Romano part of the Csa group according to the Köppen climate classification. The proximity of the Tiber is felt, which increases the humidity rate.
 The average annual temperature is 4.9 °C (40.8 °F) with August being the hottest month of the year with an average temperature of 25.2 °C (77.4 °F) while the coldest month is January with an average temperature of 5.6 °C (42.1 °F).
 During summer, from June to the end of September, daytime temperatures can reach 31 °C (88 °F) and night temperatures are around 15 °C (59 °F), while during heat waves the daytime temperatures can reach even 36 °C (97 °F).
 The average annual rainfall is 1,027 millimetres (3.369 ft), with July the driest month (28 millimetres (0.092 ft)) and November the wettest (154 millimetres (0.505 ft)).
 It is a renaissance castle committed by Nicola III Orsini in 1489 and terminated in 1493.It became a Ducal castle in 1609 when the Sforza family make Fiano as a Duchy. The castle has a rectangular plan with two defense towers and crenellated walls. The smaller tower is quadrangular with a slope in the lower part. The largest tower, called mastio, is placed in the keep, is circular and is 30 metres (98 ft) high with walls 2.7 metres (8.9 ft) wide. The castle, set in the medieval village, has its entrance on the main square of Fiano in front of the Church of Santo Stefano Nuovo. Inside there is a courtyard with a staircase leading to the main floor and from the terrace, adorned with guelph battlements, you have a view of the surrounding lands that belonged to the fief.
 The renaissance wing on the main floor is divided into nine rooms, connected to each other by doors whose jambs bear the inscription Nicolaus Tirtius Ursinus 1493, that is the date on which the works were carried out and, probably, when the frescoes were completed:
 It is a Roman campaign's manor built around the middle of the 1st century BC form the senatorial family of the Volusii Saturnini (well known by Cicero) and used until the 5th century AD. It is a perfect example of villas build in the Roman Republican age by the senatorial families not far from Rome, in a fertile and highly disputed territory from the point of view of the real estate market of the time, being not only a country residence (i.e. villa d'otium) but also headquarters of production facilities (villa rustica).
 The villa was built on an embankment that offers a panoramic view of the lower Tiber valley, extends over two levels with the upper one that housed the noble residence with a polystyle atrium, rooms on the left side, cubicles and triclinium on the right, tablinum on the bottom. The peristyle with the lararium stands on the right side of the elegant district.
 The complex was further enlarged during ages of emperors Hadrian and Traian, it underwent restorations in the 3rd-4th century AD and was frequented until the 5th century AD when a small cemetery was set up in the residential part. Then, starting from the early Middle Ages, a religious building was first built and then a small fortified center with towers and, finally, a rustic farmhouse.
 It was discovered in 1962 during works for A1 highway construction and it is actually completely bring to light. It features splendid mosaics and the remains of a series of rooms and other spaces.
 The villa can be accessed through Lucus Feronia.
 It is composed by thirteen blocks of marble finely decorated in relief with scenes of gladiator fights. 
 Dating back to the 1st century BC blocks originally adorned the tower tomb of a Roman magistrate.
 Discovered by Carabinieri Art Squad in 2007 hidden under a thin layer of topsoil in field at Fiano Romano, blocks are exposed in the antiquarium of Lucus Feroniae.

 The September Feast in honor of Our Lady of Sorrows is an event organized on the third Sunday of September in Fiano Romano in which religious traditions are relived and important celebrations and folkloristic activities take place. The 179th edition of the festival was held in 2021.
 The roots of the festival date back to 24 March 1842 when the wax image of the Holy Mary of Sorrows, dressed in satin, purchased with the offerings of the Fianesi faithful, was placed in the Church of Santo Stefano Nuovo and the diocesan bishop granted the indulgence of 40 days to all the faithful every time they visited the sacred image. In the same year the Feast of Our Lady of Sorrows was solemnized, entrusted to the women of the Pia Union of Our Lady of Sorrows (only starting from 1933 was also allowed to men to take part in the organization of the feast). After a few years of interruption, the feast was restored at the request of the faithful in 1879 and for the occasion a silk mantle embroidered in gold was purchased to embellish the image of the Madonna and, in the following years, objects were purchased and offered by the faithful of various kinds to adorn the statue. Suspended again for a few years, in 1889 the feast was resumed again and has never been interrupted since then (for example, in 1942 due to the war only religious rites were performed).
 From the 1960s the organization of the celebrations passed to the ProLoco Association (association promoting local culture and tourism) and took its current name of September Festival in honor of Our Lady of Sorrows and is organized, together with the Pia Union and the Municipal Administration, every year on the third Sunday of September. The feast begins on Thursday or Friday, the streets of the town are adorned with lights, masses and other religious moments are held in honor of Our Lady of Sorrows and moments of entertainment and socialization are also organized (sports tournaments, performance of singers, cabaret shows, games for children, popular games, horse races, rides, etc...).
 The festival culminates with the Procession on Sunday evening in which the statue of Our Lady of Sorrows is taken out of the Church of Santo Stefano Nuovo, once in the year, and is carried through the streets of the town, preceded by the Pia Union, accompanied by the musical band, followed by religious, military and civil authorities as well as by many faithful. Before her return to the Church, Our Lady of Sorrows is celebrated by a grandiose fireworks show in front of the Ducal Castle and the medieval village and, at the end of this show, all the gathered faithful greet her shouting Viva Maria. The feast ends with the blessing of the faithful by the priest in front of the entrance of the Church of Santo Stefano Nuovo before the statue makes its return into it.
