Looks familiar doesn't it? Can you guess what it is and where it's located? Well, if you guessed the Washington Monument you would be wrong. It's the Jefferson Davis Monument located in Fairview, Kentucky. Completed in 1924 it is the third tallest obelisk in the world, however it is the tallest concrete obelisk on the planet. Taller obelisks, such as the San Jacinto Monument and Washington Monument, are constructed with blocks of stone.
