At the time of the Christian Reconquest of the Iberian peninsula, some evidence point to a supposed conquest by King Afonso Henriques (1112-1185) in 1148, as well as the granting of a charter in 1180. It is known with more certainty, that the town was in the domain of the Kingdom of Portugal in 1232 with municipal organization  in 1276.

Along the 13th Century the medieval fortifications were made and unmade for the manor interests always fought with the interests of the crown and also with the population that would rather have the distant king as their lord of the manor. Finally rises the castle on the initiative of King Dinis, it was concluded during the reign of his son, Afonso IV in 1327. This is how Vide became Castelo de Vide.

The visible basic materials employed in all fortifications are stone (granite and quartzite), brick, lime plaster and clay.

Castle of Castelo de Vide  is located in the parish of Santa Maria da Devesa, town of Castelo de Vide and Portalegre District.

The castle is part of the Natural Park Serra de São Mamede, on the northern slope of the mountain, in a dominant position over the village and on the strategic line of streak, controlling in the past the crossing of the river Sever, a Tagus River affluent. This fact assured it the attention of several monarchs, expressed on several remodeling campaigns, which gave the monument its current appearance.

In the context of the conquest of Alcacer do Sal, D. Afonso Henriques  took the town from the Moors between 1160 and 1166. By the demarcation of the Castelo Branco Term in 1214  Marvão was already included in Portuguese lands. More important was that D.Sancho II  granted it a charter in 1226.

D. Afonso III  donated the lands of Marvão to the knights of the Order of Malta (1271), later on granted it to his son, Afonso Sanches, along with landlords of Arronches, Vide and Portalegre Castle.

For this reason, at the beginning the reign of D. Dinis (1279-1325), the town and its castle found themselves involved in the dispute between the sovereign and the prince D.Afonso been conquered by the forces of the sovereign in 1299. At the end of the matter, the fields of Marvão, Portalegre Arronches and were replaced by Sintra and Ourem, remaining the first held by the sovereign. This confirmed the Marvão’s charter in 1226 and embarked on its expansion and strengthening of defenses, especially the construction of the tower which began in 1300.

As were other 11th-13th-century castles, the early medieval improvements and development of Marvão castle reflect the innovations brought back by crusading orders from the near east (notably the highly influential Hospitaller castle in Syria, the Krak des Chevaliers). The medieval castle seen in Marvão today mostly post-dates the year 1299, and features numerous characteristics of a crusader-era castle: a tall central keep with raised entrance on the first floor; a series of lower, outlying turrets (some semi-circular); high-placed arrow-slits; open spaces to aid the sheltering and assembly of villagers and troops; a well, and huge rain-collecting cistern to supply water to both keep and the wider castle in the event of siege; bent entrances (both on the village and castle gates) to slow down invaders in the event of breached gates; a series of narrow killing zones (notably, in the triple gate on the village-side of the castle); extensive crenellated battlements and curtain walls that enhanced the natural defences provided by the escarpments of Marvão’s rock.

Was classified as a National Monument in 1922, by a decree on July 4th.

The Castle of Marvao is located in the village and parish of Santa Maria de Marvão, Marvão municipality, Portalegre District.

In 1570 the church became the seat of the diocese of Elvas, afterwards becoming  the cathedral . In the 17th and 18th centuries were held numerous stylistic changes that have enriched the interior. During the time of bishop D. Lawrence of Lancaster (1759-1780) the Cathedral won several altars in Estremoz marble, like the one of the main chapel held by José Francisco de Abreu. Also at that time the organ was carved with gilt a work assigned to the Italian Pascoal Caetano Lodovini. Noteworthy is also the fitted room, built in the 17th century.

The diocese of Elvas was abolished in 1881, ceasing the modifications in the temple.

During the decade of 2000  it has undergone a major restoration intervention.

In a dominant position on the so-called Mount of Graça, was part of the defense of Square-strong Elvas and City – Border Headquarters of Elvas and its Fortifications – rated from the day June 30, 2012 as World Heritage by UNESCO.

The good strategic position of the place became evident during the War of Restoration, when the Spanish troops occupied the site during the siege of the city of Elvas in the year 1658 that preceded to the Battle of Elvas lines in January 14, 1659.

In 2014, the Fort Our Lady of Graça was part of a new project of the Ministry of National Defense, created with the support of Turismo de Portugal, called Military Tourism, presenting historical itineraries based on Portuguese heroes.

The Fort of Our Lady of Grace, officially termed as Fort Conde de Lippe is  located in the parish of the Alcáçova, about a mile north of the city of Elvas, Portalegre District.

Retaken by the Moors , returned to Portuguese hands in 1220 only to fall again into the possession of the Moors. Between  1226-29  finally fell into Portuguese hands, under the reign of Sancho II (1223-1248), which granted it a Charter (May 1229) and also began the  reconstruction/strengthening of its defenses.

Considered one of the most complete medieval Portuguese military architecture, stands isolated on top of a granite hill, west to the town, in a dominant position on the confluence of Belver river with the right bank of the Tagus river, manning the so-called Line Tagus.

At the time of the Christian Reconquest of the Iberian peninsula, a wave of assaults forces the Almohad Caliphate under the Caliph Abu Yusuf Ya’qub command al-Mansur, determined the retreat of Christian boundaries to the line of the Tagus River (1190-1191) . In this context, in 1194, Sancho I (1185-1211) donated the region between the river Zêzere and the River Tagus, called Guidintesta, Guidi in forehead or Costa, the Prior of the Knights Hospitaller, Afonso Pais, for there to build a castle, called Belver by the monarch.

In 1210, when King Sancho I wrote his will, the Hospitallers received significant part of the heritage. It is believed that the castle was completed between sometime between 1210 and 1212.

During the reign of Sancho II of Portugal (1223-1248) the royal treasure was kept here.

Between 1336 and 1341, the village of Belver and its castle were one of the most important Commanderies the Hospital Order.

The 1755 earthquake caused severe damages and was abandoned for many years, being used as the town cemetery during the 19th Century.

Was after the 1909 quake that the authorities took measure into their own hands and in 1910 was considered National Monument. And it has been reconstructed since 1940 till 2005.

The Castle of Belver is located in Belver at the Gavião municipality and Portalegre District.
