The World’s Tallest Obelisk is the iconic Washington Monument, located in Washington, D.C., USA. Rising to a height of 169 meters (555 feet), this towering stone structure dominates the skyline of the American capital and remains one of the most recognizable monuments in the world.
Completed in 1884, the obelisk was built to honor George Washington, the first President of the United States. Constructed primarily from marble, granite, and bluestone gneiss, the monument reflects both classical Egyptian design and 19th-century engineering ambition.
Its construction spanned several decades due to funding challenges and the American Civil War, but the final result set a global benchmark. To this day, no other obelisk—ancient or modern—has surpassed its height.
The Washington Monument is open to visitors via elevators and stairways, offering panoramic views of the National Mall, the U.S. Capitol, and the Lincoln Memorial. Millions of tourists visit the site each year, making it a central symbol of American heritage and democracy.
