Military monument located in Cerro do Castelo, in the parish of Paderne, part of the municipality of Albufeira, in the Algarve region, Southern Portugal
 
The first military building on that site would have been a primitive Lusitanian fort conquered by the Romans, but the castle itself was only built in the 11th or 12th centuries during the Muslim period.

The monument is an Islamic fortification with a rectangular plan predominantly in rammed earth, built in the Almohad period (Berber religious power governed by the fifth Moorish dynasty, having stood out from the 12th century until the mid-13th century), and features an Albarrã tower that communicates through a round arch with the crenellated walls.

The Castle features the Albarrã tower that communicates through the round arch with the crenellated walls.

Inside, traces of houses and a longitudinal chapel are visible, and it is one of the most significant examples of Muslim military architecture in the Iberian Peninsula.

In 1248, during the reign of D. Afonso III, the castle was taken over by D. Paio Peres Correia and in 1305 under D. Dinis, after undergoing improvements, Paderne Castle was donated to the Master of the Order of Avis, D. Lourenço Anes.

In later centuries, with new strategic guidelines, Paderne Castle lost its importance and defensive function.

The albarrã tower with a square plan and the elbow door at the angle opposite the tower, defended by Barbacã, show influences from the Gothic and Manueline styles.

The access door is protected by an albarrã tower, the urbanized space with an orthogonal layout was completely planned from scratch with narrow streets run by a sewage system that carried wastewater and rainwater to the outside of the wall, the blocks are made up of houses with a central courtyard.

The fortress was taken in 1248 as part of the Christian Reconquista of the Algarve, and remained in a state of semi-abandoning after the village of Paderne moved to a new location (16th century), and was seriously damaged during the 1755 earthquake.

After the Christian conquest in 1248 by D. Paio Peres Correia, the new occupants adapted or changed the initial urban model.

Inside, among the ruins, two cisterns bear witness to the two main periods of occupation of the castle: Islamic and Christian, and next to the door is the ruined Chapel of Nossa Senhora da Assunção.

In the 16th century, pilgrimages continued to take place in the current village of Paderne until the 19th century.

Inside, there is a chapel dedicated to Nossa Senhora da Assunção, also known as Ermida da Senhora do Castelo, where it became the seat of the Parish of Paderne, but was also abandoned and entered a deep process of degradation, with only the main walls surviving.

During its operation, the church was the target of two annual pilgrimages held on August 15th, the date of the patron saint, and on March 25th, which is Annunciation Day.

The hermitage building has a rectangular plan of reduced dimensions, the altar was oriented towards the Northeast, and at a short distance there are two areas destined for the necropolis, being divided from the nave by an arch with voussoirs.

The nave had a wooden roof, while the main chapel had a vault that had three altars, and featured an image of Our Lady on its main altar.

In the basement of the hermitage, traces of a previous structure were found, probably a church built in the 13th century to adapt it for Christian worship, perhaps an ancient Islamic temple.

In the 1980s, it was the subject of archaeological research during which various fortified structures, traces of residential buildings and a church or hermitage were identified, and various materials dating from the 12th to the 18th century.

Between 2005 and 2006, conservation works were carried out on the castle walls, and archaeological prospecting work was carried out at Paderne Castle as part of the Archaeological Heritage Survey of the Municipality of Albufeira.

In February 2018, the municipality and the Regional Directorate of Culture of the Algarve restarted the Discovering Paderne Castle program, during which the castle would be reopened to the public with guided tours twice a month.

On September 10, the Minister of Culture, Luís Filipe Castro Mendes visited the fortress to monitor the conservation work on the Albarrã tower, highlighting the importance of the monument as a symbol of Albufeira, and as a promoter of cultural tourism in order to combat the municipality's image as a beach-only destination.
