Neptune Roman Tower

At the end of the 3rd century Arlon was fortified with the construction of ramparts. This castrum was 800 metres in circumference with walls that were 4 metres thick and 8 metres high with two gateways and around 20 watch towers. The Neptune tower was identical to the Jupiter tower recently discovered near to the Town Hall. The small museum consists of remains of the tower which were discovered during archaeological exca ...

Waléran, the first Count of Arlon, built a fortified chateau at the top of the town during the 11th century. Along with the town ramparts, this was completely destroyed in 1558 when Arlon was pillaged by the troops of the Duc de Guise. When the Capuchin monks arrivedin Arlon in 1621, they built their abbey on the ruins of the castle. In 1681 a Vauban-type fortified wall was built transforming the abbey into a citadel. A ...

Autelbas Castle

The current Autelbas castle was built in 1432 on the ruins of the old castle from the 13th century (destroyed in 1412 by the Burgundy army). In 1983, Autelbas Castle fell victim to a large fire and burned to the ground. It has been a ruin ever since. The last decade there have been some consolidation campaigns but it is clear that it still needs some considerable restoration works for it to survive.

Historic Site of the week

São Jorge Castle

São Jorge Castle is a Moorish castle occupying a commanding hilltop overlooking the historic centre of the Portuguese city of Lisbon and Tagus River. The strongly fortified citadel dates from medieval period of Portuguese history, and is one of the main tourist sites of Lisbon.

Although the first fortifications on this hilltop date from the 2nd century BC, archaeological excavations have identified a human presence in the Tagus valley as far back as the 6th century BC. The first fortification was, presumably, erected in 48 BC, when Lisbon was classified as a Roman municipality.

The hill was first used by indigenous Celtic tribes, then by Phoenicians, Greeks, and Carthaginians as a defensible outpost that was later expropriated by Roman, Suebic, Visigothic, and Moorish peoples. During the 10th century, the fortifications were rebuilt by Muslim Berber forces, these included the walls or Cerca Moura ("Moorish Encirclement").

Kingdom

In the context of the Christian Reconquista, the castle and the city of Lisbon were freed from Moorish rule in 1147 by Afonso Henriques and northern European knights in the Siege of Lisbon during the Second Crusade; this victory was the only notable success of that failed crusade. According to an oft-repeated legend, the knight Martim Moniz, noticing that one of the doors to the castle was open, prevented the Moors from closing it by throwing his own body into the breach, thus allowing Christian soldiers to enter at the cost of his own life. With the taking of the castle Christian forces were able to maintain the defense of Lisbon until the end of the 12th century.

When Lisbon became the capital of the kingdom in 1255, the castle served as the alcáçova, a fortified residence for Afonso III, in his role as governor. It was extensively renovated around 1300 by King Denis I, transforming the Moorish alcáçova into the Royal Palace of the Alcáçova. Between 1373 and 1375, King Ferdinand I ordered the building of the Cerca Nova or Cerca Fernandina, the walled compound that enclosed the entirety of the castle. The master builders João Fernandes and Vasco Brás were responsible for its construction. This wall, which partially replaced the old Moorish walls, was designed to encircle previously unprotected parts of the city. Completed in two years, it had 77 towers and a perimeter of 5,400 metres.

The castle and the city resisted the forces of Castile several times during the 14th century (notably in 1373 and in 1383–1384). It was during this period (the late 14th century) that the castle was dedicated to Saint George by King John I, who had married the English princess Philippa of Lancaster. Saint George, the warrior-saint, was normally represented slaying a dragon, and very was popular in both countries.

From this point onward many of the kingdom's records were housed in the Torre de Ulisses, also known as the Torre Albarrã, until the reign of Manuel I. The Portuguese National Archive is still referred to as the Torre do Tombo. Between 1448 and 1451, the master builder was paid several stipends for his work on the palace. These public works continued until 1452, with additional payments being made for labor and materials to convert the building from a fortified castle to a royal residence.

Around the early 16th century, following the construction of the Ribeira Palace beside the Tagus river, the Palace of Alcáçova began to lose its importance. An earthquake occurring in 1531 further damaged the old castle, contributing further to its decay and neglect. In 1569, King Sebastian ordered the rebuilding of the royal apartments in the castle, intending to use it as his official residence. As part of the rebuilding, in 1577 Filippo Terzi demolished one of the towers near the principal facade of the Church of Loreto. However, many of the works were never completed after the young king's apparent death during the Battle of Alcácer Quibir. The following Portuguese dynastic crisis opened the way for sixty years of Spanish rule and the castle was converted into military barracks and a prison. On 30 December 1642, Teodósio de Frias the Younger was appointed master builder to continue the works begun by his father, Luís de Frias, and his grandfather, Teodósio de Frias. This was part of a greater plan by the Spanish forces to recommission the fortification.

However, after Portugal regained its independence following the Portuguese Restoration War, the works were taken over by the Portuguese government. On 6 November 1648, Nicolau de Langres was called upon to take over the design, execution and construction of a new fortification that would surround the Castle of São Jorge and the city walls of Lisbon. In 1650 the military architect Mateus do Couto was named master builder of the project and reconstruction took on a new formality: although the military engineer João Gillot built new walls in 1652, construction again followed Couto's plans between 1657 and 1733. In 1673, the Soldiers' Hospital, dedicated to São João de Deus, was installed on the grounds beside the Rua do Recolhimento. At the end of the 17th century the Recolhimento do Castelo was constructed along the southeast angle of the courtyard, and in 1733, new projects were initiated by master Custódio Vieira.

The 1755 Lisbon earthquake severely damaged the castle and contributed to its continuing decay: apart from the walls of the old castle, the soldier's hospital and the Recolhimento were left in ruins. The necessity of maintaining a supporting military force within the capital city required expansion of the site's role of garrison and presidio. From 1780 to 1807, the charitable institution Casa Pia, dedicated to the education of poor children, was established in the citadel, while soldiers continued to be garrisoned on site. Inspired by the events of the earthquake and the following tsunami, the first geodetic observatory in Portugal was constructed in 1788 at the top of one of the towers of the castle, later referred to as the Torre do Observatório.

Republic

As part of the commemorative celebrations marking the foundation of nationhood and restoration of independence, the government of António de Oliveira Salazar initiated extensive renovations at the site. Most of the incongruous structures added to the castle compound in previous centuries were demolished and there was a partial restoration of the Recolhimento. In addition, on 25 October 1947, a monument dedicated to Afonso Henriques, presented by the city of Porto, of a replica created by Soares dos Reis (in 1887) was installed on the grounds.
