The Anaconda Smelter Stack
Coming up at number six, largely due to how many taller stacks have since been demolished, stands the Anaconda Smelter Stack located in Anaconda, Montana USA. It stands at 178.3 meters or 585 feet tall. It is also the tallest masonry structure worldwide, made of brick. It was built in 1918 and held the word record for the tallest chimney in the world from it's completion until 1937.
