Step 1 : Introduction to the question "Which of these structures is taller than the Great Pyramid of Giza?"
...For more than 4,000 years, the Great Pyramid of Giza was the tallest human-made structure on Earth, an astonishing feat for a monument built around 2560 BCE. Its record finally ended in 1221 when the completion of St. Paul’s Cathedral in London surpassed its height. Even today, the pyramid remains remarkably imposing: at 449.5 feet tall, standing taller than Big Ben, the Statue of Liberty, and the Leaning Tower of Pisa. By comparison, the Washington Monument rises to 555 feet, making it roughly 100 feet taller than the ancient pyramid.
