Belver Castle

Belver Castle occupies a steep hill beside the River Tagus, opposite the village of Belver, in the municipality of Gavião. It was the first castle built in Portugal by the knights of the Order of the Hospital and one of the most imposing that the Order raised in the country during the Middle Ages. Despite later works, it essentially preserves its original design. The national register of the Cultural Heritage, I.P. considers it one of the most representative examples of the Romanesque phase of Portuguese military architecture.

A donation by D. Sancho I

The castle’s history begins in 1194. According to the national register, which follows the historian Mário Barroca, D. Sancho I that year granted Afonso Pais, prior of the Hospital, the lands of Gimdintesta, on condition that a castle be built there. The Municipality of Gavião writes the place name as Guidintesta.

The donation responded to a difficult situation. Muslim incursions in the preceding years had pushed the Christian frontier to the line of the Tagus. The defence of the middle Tagus was shared among several institutions, but the Templars held an almost complete monopoly there. By calling the Hospitallers to Belver, the king sought to check the incursions and balance the weight of the military orders in the region.

Work progressed quickly. By 1210 the castle was already in operation: the will of D. Sancho I mentions it and states that it was one of six places in the kingdom where the royal treasure was kept. For the national register, this choice demonstrates the quality of the construction and the king’s confidence in the commander of Belver, despite its frontier position.

An oval enclosure and an isolated tower

The castle adapts to the terrain, as was typical of the period. The enclosure, of oval plan, has a wall-walk and is crenellated all around. At the centre of the courtyard rises the freestanding keep. It has a rectangular, almost square plan and three storeys. Entry was made through the middle floor, by an elevated doorway reached by a movable ladder. The top floor connected to the wall-walk by a walkway, now dismantled.

Defences are reinforced where access is easiest. The eastern face, turned towards the settlement, has four square towers. The opposite face rests on cliffs and has only two semicircular towers.

The main gate opens to the south, between two towers. The right-hand tower is sturdier and partly hides the entrance, so that anyone approaching could not easily see it. The national register notes that this arrangement only became widespread more than half a century later, in the reign of D. Dinis. The second entrance, the Porta da Traição (Gate of Treachery), lies to the west, above the steepest slope. It is also protected, between a circular tower and a projection of the wall.

From D. João I to the twentieth-century restoration

With the accession of D. João I and the wars with Castile, the castle regained military importance. In 1390, D. Nuno Álvares Pereira ordered works. Mário Barroca attributes to this campaign the cistern beside the Porta da Traição.

In the early modern period, Belver lost its military relevance. From the sixteenth century dates the Chapel of São Brás, within the enclosure. It is a Mannerist chapel with a high altarpiece of Italian influence and great devotion in the region, linked to supposed relics from the Holy Land. The 1755 earthquake caused serious damage, and in the nineteenth century the interior served as a cemetery. In the 1940s, the Directorate-General for Buildings and National Monuments (DGEMN) carried out the first full restoration. According to the national register, this campaign partly reinvented the castle, something worth keeping in mind when observing the crenellations and finials.

Classification

The castle is a National Monument under the Decree of 16 June 1910, published in the Diário do Governo no. 136, of 23 June 1910. A ministerial order of 25 February 1947, published in the Diário do Governo, II series, no. 74, of 31 March 1947, set the special protection zone, with a non aedificandi zone. The castle is not part of any UNESCO inscription.

Preparing the visit

No hours were published for the rest of the year.

Confirm hours and conditions by telephone at +351 241 639 070 or by email at [email protected].

To follow the history of the Hospitallers in Portugal, the visit continues at Crato, seat of the priory from the fourteenth century, and at the Church of Leça do Balio, the Order’s former seat in Portugal. Downriver, the Almourol Castle is another fortress linked to the defence of the Tagus. The wider context is on the page on Portuguese castles and on the page on Romanesque architecture.
