Castelo de Montemor-o-Novo

Montemor-o-Novo Castle is a medieval fortress on a hilltop above the town of Montemor-o-Novo, in Portugal's Alentejo region. Today it survives mostly as extensive ruins of walls, towers and former buildings, yet it carries real weight in Portuguese history: decisions linked to the Age of Discovery were made here.

What does the castle look like and where is it?

The fortress crowns a three-pronged hill in the municipality of Montemor-o-Novo, Évora District, roughly between Lisbon and Évora. The complex includes the defensive walls and the buildings within them. Thanks to its elevated position, the hill gives wide views over the surrounding Alentejo plains. Coordinates are approximately 38.64 N, 8.22 W.

What is the history of the castle?

The earliest occupation of the hill goes back to the Roman period. A fortification is thought to have stood on the southern prong, later destroyed or rebuilt under the Almohads in the 12th century.

During the Christian Reconquest the settlement was taken by King Sancho I, who granted it a charter in 1203 to repopulate and defend the area. Construction of the medieval castle began in this phase. Around 1310, under King Denis, major works strengthened the castle and raised new town walls, which at one stage had about 20 towers.

In the 15th and 16th centuries Montemor-o-Novo was a prosperous regional trade centre, and the fortress continued to be expanded and reinforced. In the 17th century, during the Restoration War against Spain, the defences were strengthened again, and the castle served as a first line of defence against Castile. It also played a role during the French invasions of 1808. The 1755 Lisbon earthquake caused severe damage.

Why is Vasco da Gama linked to this place?

In 1495, shortly after the death of King John II, the Cortes convened by the new king, Manuel I, met in the Palace of the Alcaides inside the castle. Historical accounts hold that the plans for Vasco da Gama's sea voyage to India were finalised at Montemor-o-Novo. For visitors interested in the Age of Discovery, this is the main reason to come.

Is the castle a protected monument?

Yes. The castle, together with its walls and the buildings within them, was classified a national monument by Decree No. 38,147 of 5 January 1951.

Who is it for?

• Fans of Portuguese history and the Age of Discovery,
• travellers driving through the Alentejo, for example between Lisbon and Évora,
• photographers looking for ruins and landscape views,
• families wanting a quiet, uncommercial place to walk.
