Why visit the castle at Monsaraz?

The castle belongs to the chain of strongholds that guarded Portugal's eastern frontier. It stands on ground of strategic value for centuries, so it layers several eras, from prehistory to the early modern period. For a traveller it offers a chance to see a well-preserved example of Portuguese defensive architecture together with wide views across the Alentejo plain.

What is the history of the castle?

Settlement on the hill goes back to prehistoric times. The site was later held by Romans, Visigoths and Muslims in turn. During the Christian Reconquista, forces led by Geraldo Sem Pavor took the fortress in 1167, but the Almohad Caliphate soon retook it. Monsaraz finally passed to Christian rule in 1232 under Sancho II. Its garrison was then entrusted to the Knights Templar and afterwards to the Order of Christ.

Work on the present castle began under Afonso III and was completed by his son, King Dinis (1261-1325). It became one of the forts Dinis kept to protect the border with Castile.

What changed in the 17th and 19th centuries?

During the Portuguese Restoration War in the mid-17th century, the defences were strengthened. A new fortification ring was built around the town in the Franco-Dutch system associated with Sébastien Vauban, with the design prepared by French engineers Nicolau de Langres and Jean Gillot.

In 1838 the county seat moved to Reguengos de Monsaraz. The castle lost its role and was abandoned, and several buildings inside the walls collapsed. Restoration began in the mid-20th century under government auspices, aiming to preserve the historical character of the site.
