They are located on Rua do Castelo, Vila de Porto de Mós, district of Leiria, in the province of Estremadura, forming part of the Intermunicipal Community of the Region of Leiria, in the region of Central Portugal
The Porto de Mós castle, built under the rubble of a Roman watch post, over the centuries suffered military, Gothic and Renaissance influences based on a pentagonal structure with reinforcing turrets at the angles and currently there are only four.
The two turrets that make up the main facade are decorated with two pyramidal domes finished in green ceramic.
Initially, Porto de Mós Castle was an Arab fortress and the Castle played an important role during the period of the Christian conquest.
D. Afonso Henriques, assisted by D. Fuas Roupinho, ended up taking possession of the town and defeating the Saracen troops commanded by King Gémir of Mérida.
In this context, the castle was handed over to D. Fuas Roupinho, who would become the first mayor of the town of Porto de Mós.
During the reign of D. Dinis, the fortress received important charitable works and in 1305 a charter was granted to the town of Porto de Mós, which had already become a municipality.
In the year 1385, the castle of Porto de Mós once again played a decisive role in the Battle of Aljubarrota, hosting the troops of D. João I and D. Nuno Álvares Pereira in the nights before the battle during which the war strategies that would give the country definitive independence were planned.
After the death of D. João I, the domain of the castle was bequeathed to his daughter and son-in-law, the Dukes of Bragança, by heredity to his grandson D. Afonso, 2nd Duke of Bragança, 4th Count of Ourém and 1st Marquis of Valença, also grandson of the constable Nuno Álvares Pereira.
D. Afonso, 2nd Duke of Bragança, the medieval Castle stopped being a watchtower and became a residential palace.
In the second half of the 15th century, D. Afonso (a cultured and well-traveled man with strong Renaissance influences that were beginning to awaken in Europe) began restoration work on the castle, which is visible to this day and was subsequently preserved and expanded by his descendants.
Over time, renovations were carried out at the Castle, but the last one carried out in 1999 allowed the castle to once again boast the shine that has always been characteristic of it.
