Elvas is a UNESCO World Heritage Site. It holds the title of the most heavily fortified city in Europe with the largest system of bulwarked dry ditches in the world. Located strategically near the Spanish border, its architecture reflects a fascinating mix of visigoth,medieval, Jewish and Moorish with the unique defensive forts and walls from 17th- to 19th-century.
When approaching Elvas from Extremadura, take the first indication to Elvas East. A series of roundabouts will lead to the turn off for the fort on the left. It will be visible from quite a distance built on a small prominence 11 kms from the border. Approaching the entrance to the fort there are many complex outer defensive structures.
As one enters the main gate crossing a moat and drawbridge the inner buildings of the fort are painted a strong ochre yellow.
There are many and various outer buidings ; barracks, stables, a chapel and at the centre the Governor's house with it's distinctive cupola and spartan interior with a narrow stairway made with stones protruding from the walls as access to the look out of the cupula. Other structures are the secret underground passageways connected to the heart of Elvas allowing provisions and personnel to move freely without exposure to the enemy forces.
Built as a five sided star shape to maximise observation and fire power this fort and many others in Portugal are often attributed to the master of military siege structures, Sébastien Le Preste Marqis de Vaubon but this is erroneous. In fact the fort was based on much earlier Italian architecture which was perfected in the 16th century as a solution to the invention of artillery fire. Vaubon studied these innovative early designs, improving and perfecting the plans and thus all star shaped fortifications are often attributed to him.
The history of Santa Luiza fort was enmeshed in the complex relationship between Spain and Portugal, creating alliances through royal marriages and inevitably political conflicts. It is a complex period of history but important to understand as it was the reason the Portuguese built so many forts to guard their border with Spain after suffering 60 years of Spanish Habsburg rule due to a melodramatic series of succession dramas which led to the Spanish king Felipe II inheriting the Portuguese crown through his mother Isabel of Portugal. A traumatic disaster for Portuguese pride and autonomy. It is worth knowing some background to grasp the reason for the extraordinary military architecture of Elvas.
The drama started to unfold with the ill fated King, Don
Sebastião of Portugal (January 20, 1554 – August 4, 1578).
The timing of the Portuguese revolt was strategic, as Spain was already stretched thin fighting in the Thirty Years' War and dealing with the Catalan Revolt, which made it difficult for Spain to mount a full reconquest of Portugal. Very shortly after the end of conflicts the Portugues, still very distrustful of Spanish intentions, began a intensive programme of building forts along the border including Santa Luzia. Construction began in 1641 with an initial sketch by governor-of-arms Matias de Albuquerque for a fort capable of housing 300 soldiers. That same year, it was redesigned by Sebastião Frias as a star fort and then re-designed again by Flemish architect Cosmander with the support of French engineer Jean Gilot . The first stone was laid on April 1, 1643, and the fort was completed in 1648
The first notable event was a heroic resistance during the siege led by Spanish commander Don Luis de Haro from October 22, 1658 to January 14, 1659 This siege preceded the Battle of the Lines of Elvas on January 14, 1659 where the fort, along with other fortifications, successfully resisted the heavy Spanish siege.
In 1706, Spanish and French troops attacked Elvas as part of the War of the Spanish Succession but failed to take the city In 1712, the fort resisted a siege by the Marquis of Bay, whose siege engines were battered by the fort's artillery. In 1801, during the War of Oranges, Spanish minister Godoy demanded the city's capitulation but failed to attack.
Peninsular War:
The city's command surrendered to the Spanish during the Peninsular War, and the fort was occupied by forces of General Francisco Solano, captain-general of the army of Andalusia. Then occupied by by French troops, who subsequently abandoned the city as part of the Convention of Sintra .
The fort served as a prison during the Portuguese Civil War (1828-1834)
It is now a military museum open every day except Monday 10.00 - 16.00 There is a small dusty museum located in former barracks. Some exhibits from the 18th and 19th centuries, nothing notable but the uniform pieces are interesting, especially the helmets.I can only imagine the one with the red plume was for running up and down the secret passageways to clean the cobwebs.
