Elvas
Portuguese frontier fortress and UNESCO World Heritage star fort
Elvas (pronounced [ˈɛlvɐʃ]), officially the City of Elvas, sits in eastern-central Portugal within the Alentejo region, in the Portalegre district. This former bishopric and frontier stronghold lies roughly 200 kilometers east of Lisbon and just 8 kilometers west of the Spanish fortress of Badajoz, along the Madrid-Badajoz-Lisbon railway line. As of 2011, the municipality covered 631.29 square kilometers and had a population of 23,078, with 16,640 people living in the city itself. The town is a prime example of the star fort (trace italienne) style in military engineering and has been a UNESCO World Heritage Site since June 30, 2012, under the name "Garrison Border Town of Elvas and its Fortifications."
Perched on a hill about 8 kilometers northwest of the Guadiana River, Elvas is supplied with clean water by the Amoreira Aqueduct, which stretches 6 kilometers. Construction began in 1498 and finished in 1622; for part of its length, the aqueduct rises 40 meters high with four tiers of stacked arches. The city was taken from the Moors in 1226 under Afonso II, briefly recaptured, and then permanently occupied by the Portuguese. It became a Roman Catholic diocese in 1570, a status it held until 1818. The late Gothic Our Lady of the Assumption Cathedral, built during the reign of Manuel I (1495–1521), shows clear Moorish influences in its design. Defenses included seven bastions and two forts: Santa Luzia and Nossa Senhora da Graça. From 1642 onward, Elvas served as the main frontier fortress south of the Tagus River, withstanding Spanish sieges in 1659, 1711, and 1801. The Battle of the Lines of Elvas in 1659 saw the garrison and townspeople help rout a Spanish army. During the Peninsular War, French forces under Marshal Junot captured the city in March 1808 but evacuated it that August after the Convention of Sintra. The nearby fortress of Campo Maior, 15 kilometers to the northeast, is noted for its Napoleonic-era siege by the French and relief by British troops under Marshal Beresford in 1811, an event later commemorated in a ballad by Sir Walter Scott.
The UNESCO site, added in 2012, encompasses the Garrison Border Town of Elvas and its Fortifications. Heavily fortified from the 17th to 19th centuries, it boasts the largest bulwarked dry ditch system in the world. Inside the walls are barracks, military buildings, churches, and other structures, many desi

Lore & Background
Elvas lies on a hill 8 kilometres northwest of the Guadiana river. The Amoreira Aqueduct, 6 kilometres long, supplies the city with clean water; it was begun in 1498 and completed in 1622. For some distance it includes four tiers of superimposed arches, with a total height of 40 metres. The city was wrested from the Moors in 1226 under Afonso II but was temporarily recaptured before its final occupation by the Portuguese. In 1570 it became an episcopal see, the Roman Catholic Diocese of Elvas, until 1818. The late Gothic Our Lady of the Assumption Cathedral, which has many traces of Moorish influence in its architecture, dates from the reign of Manuel I of Portugal (1495–1521). The fortifications were designed by the Flemish-born Portuguese Jesuit Padre João Piscásio Cosmander.
Reader's Guide
Elvas was defended by seven bastions and the two forts of Santa Luzia and the Nossa Senhora da Graça Fort. From 1642 it was the chief frontier fortress south of the Tagus, which withstood sieges by the Spanish in 1659, 1711, and 1801. Elvas was the site of the Battle of the Lines of Elvas in 1659, during which the garrison and citizens of the city assisted in the rout of a Spanish Army. The Napoleonic French under Marshal Junot took it in March 1808 during the Peninsular War, but evacuated it in August after the conclusion of the Convention of Sintra. The site, extensively fortified from the 17th to 19th centuries, represents the largest bulwarked dry ditch system in the world. The fortifications were designed by Dutch Jesuit Padre João Piscásio Cosmander and represent the best surviving example of the Dutch school of fortifications anywhere. The UNESCO site includes the Amoreira Aqueduct, Historic Centre, Fort of Santa Luzia and the covered way, Nossa Senhora da Graça Fort, and the fortlets of São Mamede, São Pedro, and São Domingos.
