Castle of Numão

The Castle of Numão stands in the municipality of Vila Nova de Foz Côa, Portugal, on a site first occupied during prehistoric times. The earliest known builders were the Lusitanians, an ancient Iberian people who established a fortified settlement here, which was later adapted and Romanized during the Roman occupation of the peninsula.

In the early medieval period, the site underwent several changes in control. During the Christian Reconquest, the castle belonged to D. Chamoa Rodrigues and was donated to the Monastery of Guimarães in 960 by his aunt, Countess Mumadona Dias. This early medieval phase saw the castle as a monastic possession. Around the year 1000, Muslim forces retook the fortress, holding it until it was destroyed in 1030 by the brothers Tedom and Rausendo Ramires. Subsequently, the castle returned to Christian rule under Fernando Magno in 1055 or 1056, at which point it was again listed among the property of the monastery by 1059.

Following the independence of Portugal, King Afonso Henriques (1112-1185) granted the castle and surrounding lands to his brother Fernão Mendes de Bragança. Fernão Mendes issued a formal charter to the town, at that time called Civitate Noman, on July 8, 1130, initiating the castle’s reconstruction. Later, under King Sancho I (1185-1211), the castle’s defensive walls were restored and a keep tower constructed, an effort commemorated by an inscription dated to 1189, which was recorded in the 18th century but no longer exists.

During King Sancho II’s reign (1223-1248), the castle and its lands were temporarily given to Abril Peres de Lumiares. The town’s privileges were confirmed again in 1265 by King Afonso III, who also oversaw further fortification work. King Dinis reconfirmed the charter in 1285 and continued strengthening the castle’s defenses.

The castle played a role in the 1383-1385 Portuguese succession crisis when Numão was one of the strongholds that supported Beatriz’s claim to the throne. In 1436, during King Duarte’s rule (1433-1438), a legal status known as a couto de homiziados was established at Numão, indicating the area had difficulties maintaining stable settlements. Later, King Manuel I granted a new charter on August 25, 1512, by which time the castle fell under the administration of the Order of Christ as a commandery. Records from 1527 show that the town contained 15 households, with 41 additional residences in the nearby lands.

From the 14th century until 1534, the strategic defense of the castle was in the hands of the Coutinho family, whose extinction hastened the decline of the site. By the late 18th century, the original village was relocated away from the hilltop to the surrounding lowlands, and the castle had largely fallen into ruin. Nevertheless, an inscription confirming the keep tower’s construction date in 1189 was still legible on the west gate at that time, as noted by Frei Joaquim de Santa Rosa de Viterbo around 1798-1799.

In recognition of its historical value, the Castle of Numão was officially classified as a National Monument in 1910. Efforts to stabilize and restore the fortifications began in the 1940s. These included repairs and cleaning, rebuilding sections of wall, clearing the cistern, and restoring the keep tower. Further restoration took place in the 1970s and again in the 1980s following the collapse of part of the northern wall. In the 21st century, the municipality added lighting to highlight the monument’s presence.
