[3] The Ara Romana to Deus Jupiter Depulsori (which still survives to this day in Saldanha), is one of these remnants of this period (it was constructed during the reign of Septimius Severus in the 3rd century AD).

[3] Vestiges of the Visigothic era are rare, but include a paleo-Christian inscription that was discovered in São Martinho do Peso (now in the Abade de Baçal Museum in Bragança.

[3] Moorish influence in this region is limited to local handicrafts made from flax and wool, that includes the hand embroidery, quilts, rugs and towels.

The regions name evolved from this settlement: Mógo means a implanted marker, considered a symbolic delineation of the separation or division of a territory, a term imported from common language at the time.

The stone of the cell-block tower is inscribed with a medieval statement: "Começaram os fundamentos do Castelo chamadao Pena Roia na era de 1204 sendo Mestre Geral dos Templários Gualdim Pais" [They began the fundamentals of the Castle Pena Roia in the era of 1204 by Master General of the Templar Gualdim Pais].

During the Portuguese dynastic crisis (or Interregnum) the noble classes supported the King of Castile, resulting in an eventual reprisal by Prince John (who elevated the hamlet of Azinhoso and parsed it from Mogadouro).

[3] Mogadouro, historically, fell within the Caminhos de Santiago, a capillary of secondary roadways that extended throughout the Trás-os-Montes region leading pilgrims down Saint James Way.

The Távora family, a noble house with influence and power in court, controlled the region, commanding the fort and guiding the town, generally contributing to the development of the lands within their domain.

After the extinction of the monastic orders, by the Liberal government, the Convent of São Francisco was appropriated to store public records and local administration.

[3] By the end of the 20th century, only the poet-jurist José Francisco Trindade Coelho defended his land rights, and the region was abandoned by the central hierarchy of Lisbon.

A great part of the territory of the Mogadouro belongs to the Mirandês Plateau (which is an extension of the Iberian Meseta), lands rich fertile fields responsible for the cultivation of cereals (such as wheat, oats, and rye), supporting cattle and sheep herds (including the Mirandese and Terra Quente breeds).

The area around the Douro is a zone of granite escarpments of large blocks, resulting in a relief that is shaped by schists interrupted by quartz rocks that form the mountains.

The municipality of Mogadouro has, over the last decades, suffered an enormous depopulation, resulting in the concentration into the urbanized areas, and emigration to the coastal communities of Portugal.

Administratively, the municipality is divided into 21 civil parishes (freguesias):[4] Mogadouro is essentially a rural area, supported by agriculture and animal by-products.

Local cheeses (goat and sheep), honey, económicos, roscos, matrafões, folar da Páscoa, rosinhas (a traditional sweet from Bruçó), formigos and tantas round out the peculiar digestive and aperitifs of the region.
