The Monument dated 1968, designed by the sculptor Leopoldo Almeida, representing Commander Nuno Álvares Pereira who defeated the Castilian army in the battle of Aljubarrota.

Work from the 20th Century (1966-1968), by the sculptor Leopoldo de Almeida, represents Nuno Álvares Pereira, soldier and strategist of the Battle of Aljubarrota, the Constable.

Nuno Álvares Pereira (1360-1431), an unavoidable figure of the Middle Ages, professed as a simple brother in the Carmelite community of the Convento do Carmo in Lisbon, he was canonized by Pope Benedict XVI in April 2009 and became known as Saint Nuno de Santa Maria.

D. Nuno Álvares Pereira, at the age of 16, in 1376 married Leonor de Alvim, four years older, a rich, childless widow from a first marriage, in a ceremony held in Vila Nova da Rainha, a parish in the municipality of Azambuja.

The noble couple settled in Minho (it is assumed that in Pedraça, Cabeceiras de Basto), on a property owned by D. Leonor de Alvim.

The father, with this marriage, guaranteed his son's future, since Nuno could not succeed him in the position of prior, this position passed to his brother Pedro who would end up taking the side of Castile.

In his marriage to Leonor de Alvim, three children were born: two boys who died young and a daughter who reached adulthood and had descendants: Beatriz Pereira de Alvim who became the wife of D. Afonso, 1st Duke of Bragança, giving rise to the House of Bragança that would reign in Portugal three centuries later.

Nuno Álvares Pereira also known as the Holy Constable, formally São Nuno de Santa Maria or simply Nun''''Alvares (Paço do Bonjardim or Flor da Rosa 24 June 1360 – Lisbon, 1 November 1431), was a Portuguese nobleman and general of the 14th century.

Nuno Álvares Pereira played a fundamental role in the crisis of 1383-1385 where Portugal defended its independence from Castile.

Nuno Álvares Pereira was also 2nd Constable of Portugal considered the Portuguese strategist, commander and military genius of all time, he commanded forces substantially inferior in number to the enemy and won all the battles he fought and the patron saint of the Portuguese Infantry.

His way of commanding was characterized by example and countless military virtues among his men.

On August 14th, D. Nuno Álvares Pereira showed his military genius by winning the battle of Aljubarrota. The battle would prove decisive in the end of the political instability of 1383-1385 and in the consolidation of Portuguese independence. After the Castilian threat ended, D. Nuno Álvares Pereira remained Constable of the kingdom and became Count of Arraiolos and Barcelos.

After the death of his wife, he became a Carmelite (he entered the Order in 1423, in the Convent of Carmo, which he had built in fulfillment of a vow), took the name Brother Nuno de Santa Maria, and remained there until his death, which occurred on November 1, 1431 (All Saints' Day) at the age of 71, surrounded by the king and the infants.

In the last year of his life, King D. João I paid him a visit in Carmo. D. João always considered that Nuno Álvares Pereira was his closest friend, who would place him on the throne and save Portugal's independence.

The tomb of Nuno Álvares Pereira was destroyed in the 1755 Earthquake. His epitaph was: "Here lies that famous Nuno, the Constable, founder of the Most Serene House of Bragança, excellent general, blessed monk, who during his life on earth so ardently desired the Kingdom of Heaven after death, and deserved the eternal company of the Saints. His earthly honors were countless, but he turned his back on them. He was a great Prince, but he became a humble monk. He founded, built and dedicated this church where his body rests."
