Marta is a comune (municipality) in the Province of Viterbo in the Italian region of Latium, located about 80 kilometres (50 mi) northwest of Rome and about 20 kilometres (12 mi) northwest of Viterbo. Marta borders the following municipalities: Capodimonte, Montefiascone, Tuscania, Viterbo. Marta is on the southern shore of Lake Bolsena near the source of the Marta River.

Lake Bolsena (Italian: Lago di Bolsena) is a lake of volcanic origin in the northern part of the province of Viterbo called Alto Lazio ("Upper Latium") or Tuscia in central Italy. It is the largest volcanic lake in Europe. Roman historic records indicate activity of the Vulsini volcano occurred as recently as 104 BC; it has been dormant since then. The two islands in the southern part of the lake were formed by underwater eruptions following the collapse that created the depression. The lake is supplied entirely from the aquifer, rainfall and runoff, with one outlet at the southern end. A sewage treatment plant filters most of the raw sewage from the surrounding communities. Constructed in 1996, it features pipelines transporting the sewage from every major community around the lake to the treatment plant on the Marta River; that is, no effluents enter the lake. Fertilizers are a second source of contamination. However, the chemical content of the lake is monitored at several stations around it. The lake has a long historic tradition. The Romans called it Lacus Volsinii, adapting the Etruscan name, Velzna, of the last Etruscan city to hold out against Rome, which was translocated after 264 BC, and its original location today has not been securely identified. The lake is bordered on one side by a modernized version of the Roman consular road Via Cassia. In addition to the historic sites of all periods, Lake Bolsena is currently surrounded by numerous tourist establishments, largely for camping, agrotourism and bed and breakfasts. One third of the lake was donated to the Catholic church by the noble family Alberici of Orvieto. In recognition of the donation, the Alberici family was honored with a ceremony three times a year performed by the Bishop of Orvieto.

Vulsini, also known as Volsini volcano, Vulsini Volcanic District, Vulsini Volcanic Complex and the Vulsinian District, is a circular region of intrusive igneous rock in Lazio, Italy, about 87 km (54 mi) to the north northwest of Rome, containing a cluster of calderas known to have been active in recent geologic times. The Vulsinian region is one of dozens of intrusive circular regions, most smaller than the Vulsinian, arranged in a band from Campania through Lazio, called the Roman Comagmatic Province. A comagmatic province is a geologic area of the same type and age igneous rock deriving from the same crustal magma. The Roman region is post-collisional; that is, the intrusions were not a result of the lateral stresses that created Italy and raised the Apennines, but were subsequent to Italy's creation. The Volsinian is the northernmost region. At relatively low altitude, the Vulsini calderas cover about 2,280 km2 (880 sq mi) and contain four Pleistocene-age depressions known as Bolsena, Latera, Vepe and Montefascione calderas. An alleged eruption occurred in 104 BC, but it is currently considered a misinterpretation of the description of a fire, and the most recent confirmed activity occurred in Pleistocene. The largest, the Bolsena caldera, which is roughly 16 km (9.9 mi) across, is filled with the waters of Lake Bolsena, which derive mainly from deep aquifers. Immediately to the northwest are the combined Latera and Vepe calderas, about 8 km (5.0 mi) by 11 km (6.8 mi). Vepe, to the north of Lake Mezzano (a very small crater lake west of Lake Bolsena) is what is known as a nested caldera; it arose in the previously existing Latera Caldera. Italian routes SS74 and SS312 follow the rim from Valentano through Latera westward, turning off before Mezzano on the other side. In addition the small Montefiascone caldera, also nested, lies between Montefiascone on its eastern rim and the lake. Two islands in the lake, Bisentina and Martana, were formed from airfall tuffs in Pompeii-like eruptions. Dozens of other tuff cones dot the region, mainly on the eastern side of the complex.The Italian Civil Protection Department considers Vulsini as extinct.

The Museum of Farnese Garments is on the third and fourth floor of Palazzo Farnese in Gradoli, Viterbo, Italy. It was inaugurated in December 1998.The Museum is divided into different rooms, where there are large reproductions of clothes of both the nobility and commoners, including underwear, accessories, weapons, armors and jewelry of the Renaissance. The clothes have been recreated by observation of frescoes, painting and prints of the 15th, 16th and 17th centuries.

Piansano is a comune (municipality) in the Province of Viterbo in the Italian region of Latium, located about 90 kilometres (56 mi) northwest of Rome and about 25 kilometres (16 mi) northwest of Viterbo. As of 31 December 2004, it had a population of 2,232 and an area of 26.5 square kilometres (10.2 sq mi).Piansano borders the following municipalities: Arlena di Castro, Capodimonte, Cellere, Tuscania, Valentano.

Lake Mezzano (Italian: Lago di Mezzano; Latin: Lacus Statoniensis) is a small crater lake of central Italy, of volcanic origin, which was formed 400,000 years ago.The lake has a circular shape typical of crater lakes. Its surface area is 475,000 m2 the altitude of its surface is 452 m and has a perimeter of 2,516 m. The emissary which leaves Lake Mezzano is river Olpeta, that is an affluent to Fiora. The lake lies in the territory of the community of Valentano (VT).In the 1980s an archaeological campaign brought back to light a number of historical and prehistorical findings. Many of those are now exhibited in the Museo della Preistoria e della Rocca Farnese in Valentano.

Casone is a village in Tuscany, central Italy, administratively a frazione of the comune of Pitigliano, province of Grosseto, in the tuff area of southern Maremma. At the time of the 2001 census its population amounted to 130.Casone is about 80 km from Grosseto and 9 km from Pitigliano, and it is situated along the Provincial Road which links Pitigliano to the province of Viterbo and Lazio.

Montefiascone Cathedral or the Basilica of Santa Margherita (Italian: Duomo di Montefiascone; Basilica Cattedrale di Santa Margherita) is a former Roman Catholic cathedral in Montefiascone in the province of Viterbo, Italy, dedicated to Saint Margaret of Antioch, the patron saint of the town. It was formerly the episcopal seat of the Diocese of Montefiascone (suppressed and incorporated into the Diocese of Viterbo in 1986) and is now a basilica minor (status bestowed in 1943). It is one of the most important churches in the area, and has one of the largest domes in Italy (27 m of diameter), which is visible from most of the towns of the Viterbo area.

Sant'Andrea in Campo is a Romanesque style, Roman Catholic church in Montefiascone, province of Viterbo, Italy.

Farnese is a comune (municipality) in the Province of Viterbo in the Italian region of Latium, located about 100 kilometres (62 mi) northwest of Rome and about 35 kilometres (22 mi) northwest of Viterbo.

Rofalco was a fortified late-Etruscan settlement, located about twenty km north of Vulci, at the edge of the Selva del Lamone volcanic plateau. The site controlled the important natural route formed by the valley of the Olpeta stream and contributed to the defense and the organization of the southeastern portion of the ancient territory of Vulci.Known at least since the 1970s, the site was explored for the first time systematically by the Roman Archaeology Association in 1981 and soon taken into account in several studies concerning the territory. Regular excavations were started in the summer of 1996 by Mauro Incitti, with the additional goal of counteracting the damage caused by looters. In recent years, in addition to research activities, an outreach project concerning all aspects of the site has been gradually developed in accordance with the different institutions in charge. The nineteen annual excavations that have been carried out up till now were done by more than 550 Italian and foreign volunteers, who investigated the defensive structures and several of the buildings of the town.
