How did they make the Washington monument?

The Washington Monument was constructed using a combination of marble, granite, and blue stone from various quarries. The project began in 1848 but faced interruptions, including funding issues and the Civil War, leading to its completion in 1884. The monument's design features a simple, obelisk shape, and it stands at 555 feet tall, making it one of the tallest structures in the world at the time. The construction involved a technique called "lifting," where blocks of stone were raised into place using cranes and pulleys.
