Village
Viana do Bolo is a town of about 2,700 inhabitants overlooking an arm of the Bao reservoir, on the río Bibei, at the heart of a comarca known as the Maxia Verde of Galicia, with high mountains and deep valleys. At 271.51 km², it is the second-largest municipality in Ourense after La Vega, and it was the seat of a judicial district until 1965. Agriculture, limited by the climate and land fragmentation, centres on the chestnut, which is in great demand, while livestock farming, especially cattle, sustains strong meat production. Its first settlers established themselves in a hillfort where the town now stands, linked to the tribe of the bíbalos and to the ancient Forum Bibalorum. Its medieval tower houses an ethnographic museum, and its entroido, with the boteiros in embroidered costume, culminates in the Festa da Androlla.
Monument
The only remnant of the medieval castle, this square tower of about 33 metres high dates back to the 9th century, when it was raised for defence against the Muslims; destroyed and rebuilt in 1180 by order of Ferdinand II, it was rebuilt again in the 15th century after successive conflicts. Philip II made it the seat of a marquisate in favour of Pedro Pimentel, who placed on it the coat of arms that still adorns the façade today. It retains the entrance door to the parade ground and the one to the courtyard of honour, and during the 19th-century Carlist wars it was again the scene of clashes; during the civil war it served as a prison. Declared a historic-artistic monument in 1949, it today houses the Viana ethnographic museum.
Monument
A church of late Romanesque origin, of the end of the 12th century, of which the north and south walls survive with windows of double horseshoe arches in the Mozarabic tradition; the tall and very plain bell tower was raised in the 19th century.
Monument
A church of Romanesque origin, the main monument of the parish of San Cibrao (Viana do Bolo), which was once part of a convent of the Order of the Temple; of its original fabric only the simple western portal survives, covered by an open lean-to roof. It has a basilical plan with three naves, something unusual in the area, separated by round arches on monolithic Doric columns. Documentation of the monasterium Sancti Cypriani traces its origin back to the year 916.
Monument
A church raised in the 13th century, already at the transition from Romanesque to Gothic, of which barely anything original remains beyond the main doorway, crowned by an austere pierced rose window; inside it preserves a Baroque altarpiece.
Monument
A parish church of Romanesque origin remodelled in the Baroque period, when it received the three altarpieces that today preside over the nave; together with Santa María de Viana and San Pedro de Grixoa it makes up the municipality's trio of medieval churches.
Monument
A Neoclassical sanctuary of the 17th century raised on the height of Quintela, above the Bibei valley; it draws one of the best attended pilgrimage festivals in the comarca on Trinity Sunday and a circular route of some ten kilometres starts from it.
Monument
A Baroque chapel in the town which guards an articulated Christ kept in a glass case, an image used in the Deposition processions during the Semana Santa of Viana.
Monument
A 17th-century great house in the parish of Fradelo, with its own chapel, fountain and dovecote inside the grounds; it is one of the four pazos dotted about the countryside of Viana do Bolo, along with those of Grixoa, Punxeiro and Oumoso.
Monument
An 18th-century pazo built by the Gaioso family, laid out around a central courtyard and topped by a tower; it preserves a chapel and farm buildings within the walled ensemble.
Monument
A manorial ensemble in the hamlet of Punxeiro whose chapel, dated 1736, displays on its façade the coats of arms of the lineages that owned the house and its farmland.
Monument
An 18th-century great house laid out around an inner courtyard, with a chapel and farm buildings, today privately owned; in the same hamlet water mills and a traditional fountain are also preserved.
Monument
A group of flour mills stepped along the River Camba, in the hamlet of Pradocabalos, where the villagers ground their rye in turns well into the 20th century; they form part of the municipality's ethnographic inventory.
Nature
A castro enclosure known as O Castelo, in the parish of Covelo, one of the seven fortified settlements catalogued in the municipality along with those of Punxeiro, Grixoa, Pontón and Quintela de Edroso.
Curiosity
A Roman gold working in the parish of Caldesiños, where washing the ground away with water left a landscape of cuttings and channels that has been compared with Las Médulas; a viewpoint takes in the whole site.
Curiosity
A communal wolf trap on a cross-shaped plan, some hundred metres to a side and two metres high, towards whose centre the villagers used to drive the animals; it was restored and consolidated in 2019 after decades of neglect.
Curiosity
A spa of sulphurous waters that operated from the end of the 19th century until 1958, with its own hotel and bathhouse; today its ruins, overrun by vegetation, can be visited beside the spring that gave rise to it.
Curiosity
A large cross built with local stone bonded with cement beside a recreation area in the parish of Grixoa; it is an example of popular devotional architecture that has become a landmark in the local landscape.
Nature
A centuries-old chestnut tree in the parish of Hedroso, considered one of the most massive and long-lived specimens in Galicia; it grows in a traditional chestnut grove of the kind that supplied the whole comarca with chestnuts for centuries.
Nature
A carballo of the species Quercus robur of exceptional size which gives its name to the oak grove where it grows; it is the most notable tree in a municipality dominated by chestnut groves, oak woods, birches and conifers.
Nature
A reservoir on the River Bibei that floods some 820 hectares and surrounds the promontory on which the town stands, turning the old town into an all but peninsula; its slopes are crowded with chestnut groves and steeply pitched vineyards.
Nature
A dam raised in 1961 on the River Bibei, on the boundary between Galicia and the province of Zamora, so that the reservoir basin itself marks the administrative border between the two regions.
Nature
Before joining the Sil, the Bibei cuts a canyon of some forty kilometres with drops of up to 500 metres; on its slopes terraced vineyards survive, along with one of the oldest riverside woodlands in Spain.
Nature
A natural balcony at 1,290 metres of altitude above Quintela de Edroso, from which a good part of the Bibei valley can be taken in, along with the ranges that separate the province of Ourense from that of Zamora.
Nature
A waterfall on the Corgas stream, in the parish of Pexeiros, which plunges among blocks of granite; its flow is especially striking after rain and after the snowmelt in the ranges to the east.
Nature
A mountain chain that tops 1,200 metres of altitude and closes the municipality off to the east, separating the Bibei valley from the uplands of A Gudiña; its name refers to the scarcity of surface water on its ridges.
Activity
Carnival of Viana do Bolo, the oldest and most traditional in the area, declared Fiesta de Interés Turístico de Galicia (Festival of Tourist Interest of Galicia); its central figure is the boteiro, a black-faced masked figure who clears the way with great leaps supported by the monca, accompanied by the folións, percussion troupes that ward off meigas and meigallos. The calendar opens with Compadres Thursday, when the men throw flour at the women, and continues with Comadres Thursday, with the roles reversed; Fat Sunday brings the great parade of floats and troupes, with a lunch whose centrepiece is the androlla, and Shrove Tuesday of the Entroido closes it with a flour battle and the night-time burning of the Lardeiros. Its origins are unknown for lack of documentation, though one theory places them in pre-Roman agricultural rites.
Activity
A gastronomic contest held on Fat Sunday dedicated to the androlla, a sausage of minced, seasoned pork rib smoked in the traditional way; in February 2026 it held its fifty-fourth edition. The androlla is made with pork rib, paprika, salt and garlic, stuffed into the widest section of the large intestine, and sometimes also includes pieces of rind; it is eaten mostly boiled, accompanied by cachelos and vegetables or by a cocido, though it can also be roasted in the oven or grilled. It is a typical dish of south-eastern Ourense, Lugo and El Bierzo, and besides in Viana do Bolo it has its own festival in the town of Navia de Suarna, in Lugo province. The name comes from the French andouille, already documented in the Middle Ages.
Activity
A gathering born in 2015 which every January brings to Viana do Bolo winter masquerades from various parts of Spain, Portugal and Italy, alongside the local boteiros and folións.
