Montemor-o-Novo Castle is located in the parish of Nossa Senhora da Vila, in the municipality of Montemor-o-Novo, in the district of Évora, in Alentejo, Portugal.
In a dominant position on the highest hill in the region, the castle originally sheltered the village within its walls, which, as it developed, expanded along the slope to the north. Historical documents confirm that Vasco da Gama finalized his plans for his voyage to India in this castle.
Background
The earliest human occupation of this site possibly dates back to a prehistoric Romanized fort, according to the abundant archaeological evidence in the region. This was where the Roman roads from Santarém and the mouth of the River Tagus met, continuing via Évora to Mérida. The site would have been fortified for this reason.
Centuries later, during the Muslim invasion of the Iberian Peninsula, the name Almançor remained in the region, in the toponymy of the Almansor river. Some authors claim that there was also a Muslim fortification here.
The medieval castle
During the Christian reconquest of the Iberian Peninsula, the town was conquered by Portuguese forces under the command of D. Sancho I (1185-1211). With a view to repopulating and defending it, the sovereign granted it a Charter in 1203. It is believed that the construction of the medieval castle began at this stage.
During the reign of D. Dinis (1279-1325), major reforms were undertaken to the town's defences, including the construction of the town's fence, which was completed in 1365.
Once the Avis dynasty was established, the domain of Montemor-o-Novo became a third part of the lordship of Constable D. Nuno Álvares Pereira.
Throughout the 15th century, the castle underwent renovation work, carried out by master stonemason Afonso Mendes de Oliveira. In the 15th and 16th centuries, the town reached its greatest prosperity, due not only to regional trade, but also to the fact that the Court remained for long periods in Évora, which made the town the scene of events such as the Cortes of 1495, when King Manuel I (1495-1521) decided to discover the sea route to India. This sovereign granted the town a new charter in 1503. Later, under the reign of King Sebastian (1557-1578), it was granted the title of Notable Town (1563), considering it to be an ancient place with a large population.
