Vulcan

The Vulcan statue is the largest cast iron statue in the world, and is the city symbol of Birmingham, Alabama, United States, reflecting its roots in the iron and steel industry. The 56-foot tall statue depicts the Roman god Vulcan, god of the fire and forge, with ironworking equipment. It was created as Birmingham's entry for the Louisiana Purchase Exposition in St. Louis, Missouri. While it is the world's largest made of iron, it is also among the nation's tallest statues of any kind.
