The bridge over the Tagus at Almaraz was built by Emperor Carlos I in the 16th Century and was known by the local people as the Albalat Bridge; however, it was destroyed by the Spanish on March 14, 1809 to prevent its use by the French during the Peninsular War. In the Battle of Almaraz on 18/19 May 1812, the Anglo-Portuguese Army under Lord Hill destroyed a French pontoon bridge across the Tagus which was protected by two French garrisons at either end.
