Badajoz Fortress
During the Peninsular War, the British conquered Badajoz Fortress, a bastion built in the 12th century. The Almohads built the castle in the 12th century, while it was most likely present when Badajoz was created in the 9th century. During the Peninsular War, the British attempted three times to seize Badajoz Fortress from the French.
Between March 16 and April 6, 1812, an Anglo-Portuguese force led by Arthur Wellesley, the (future) Duke of Wellington, besieged and eventually breached the high curtain walls of Badajoz Fortress.
