Forte de Santa Luzia

A 17th-century star-shaped fortress in Elvas, Alentejo, Portugal, constructed 1641-1648 to defend the border town during the Portuguese Restoration War. The first stone was laid on 1 April 1643 under plans by the Dutch military engineer Cosmander. By 1644 the fort withstood a siege by the Marquis of Torrecuso, and in 1658-1659 it resisted the heavy Spanish siege during the Battle of the Lines of Elvas. Classified as a National Monument since 1940 and part of the UNESCO-listed Garrison Border Town of Elvas (2012), it has housed the Army Museum since 2001 with collections of medieval to 19th-century weapons.
