The fortress around the town guards an important cross-border road from Spain, and underwent several sieges. The town was captured by Spain in 1762 during the Seven Years' War. In 1810 and 1811, Almeida was the site of two important sieges during the Peninsular War. The siege of 1810 ended spectacularly when a chance shell ignited the main gunpowder magazine, which exploded, killing 500 defenders and destroying most of the town .
