History
Castell de Sant Jordi d’Alfama is a medieval castle and later coastal fortress in Spain, on a point of the Gulf of Sant Jordi in the municipality of l’Ametlla de Mar. Standing beside an ancient Roman road between Coll de Balaguer and the mouth of the Ebro, it controlled a compulsory passage for land and maritime routes.
Medieval foundation and the Order of Saint George
The first documentary reference to Alfama dates to 1201. Pedro II of Aragon and Ramon de Montcada then transferred the place to Joan d’Almenara, Martí de Vidal, a subdeacon, and their successors. The grant required them to establish a convent and hospital dedicated to God and Saint George under the authority of the Church of Tortosa.
This religious community developed into the Order of Saint George of Alfama, a medieval military-religious order that combined conventual life with the defense and settlement of coastal or frontier areas. The order was recognized by the pope in 1373. Its foundation sought to repopulate the sparsely inhabited territory between Tortosa and the rest of Catalonia while protecting the coast from maritime piracy. The monarchs granted privileges to support these aims, but attempts to attract settlers did not succeed.
The order reached its greatest prosperity during the fourteenth century. Around 1400, it was incorporated into the Order of Santa Maria of Montesa, another military order in the Crown of Aragon. Montesa abandoned the fortress late in the same century, after which Alfama remained under Tortosa’s jurisdiction and was reduced to a priory, a religious establishment governed by a prior and subordinate to a larger religious house.
Restoration, destruction, and rebuilding
Following a lawsuit, the Order of Montesa regained control of Alfama in 1575, and the priory was restored the following year. An inventory made in 1576 describes the medieval complex in detail, including its fortified body, courtyard, church, dormitory, chapter room, refectory, and lookout tower.
During the Guerra dels Segadors, or Reapers’ War, a seventeenth-century revolt and conflict in Catalonia involving French and Catalan forces, the site was bombarded in 1650. The attack was intended to prevent those forces from fortifying it, and the old complex was reduced to ruins.
The reorganization of coastal defenses in the late seventeenth and early eighteenth centuries brought a new phase of construction. The complex was rebuilt according to the Vauban system, a bastioned method of fortification using angled defenses, bastions, ravelins, and protected approaches against artillery. Undamaged ashlar blocks from the medieval fortress were reused, although the new fort stood somewhat farther inland. Constructed in 1732 and 1733 during the reign of Philip V of Castile, it was intended to monitor maritime routes, and much of the surviving fabric belongs to this phase.
Conservation and legal protection
A restoration and conservation campaign in 1985 consolidated parts of the complex and cleared its interior. The site is included in the Architectural Heritage Inventory of Catalonia and is protected as a Cultural Asset of National Interest and as a Spanish Asset of Cultural Interest with the status of historic monument. Its declaration dates to 28 October 1976.
Remains
Medieval castle
The medieval castle survives in a ruinous condition. Some areas retain fragments of the lower wall courses, while elsewhere only traces defining the ground plan remain. The walls were built of rubble stone, and the poor survival of the medieval fabric reflects both its destruction and the removal of stone for the eighteenth-century fort.
The remains follow a trapezoidal plan adapted to the terrain, with wall sections surviving on the south, west, and north sides. At the southwest angle, part of a wall is made from large, well-squared stone blocks that begin almost at sea level and meet surviving rock. The medieval construction probably included a damaged tower and lower-level interior spaces.
The 1576 inventory describes the original complex as a roughly square fortified body measuring about 20 metres on each side, with exterior walls measuring about 56 palms. A courtyard occupied the center. The dormitory stood on one side and the church on another, while other conventual rooms, including a chapter room and refectory, brought the total to eight rooms. The inventory also mentions a lookout tower.
Modern fortress
The adjoining modern fortress has a lower polygonal courtyard enclosed by towers, bastions, and ravelins. Two thick parallel walls were connected at the front by a third wall forming a segmental arch. Together, these defenses protected interior towers and rooms arranged around the central courtyard. An entrance in one of the four walls was shielded by two projecting lines of masonry.
Torre de Sant Jordi d’Alfama
The ruins of the Torre de Sant Jordi d’Alfama stand beside the castle. This optical-telegraph tower transmitted signals visually between elevated stations and probably served as the Salim watchtower.
