Monumental structures are large and impressive buildings or monuments that often serve as symbols of cultural, historical, or architectural significance. Examples include the Great Wall of China, the Pyramids of Giza, and the Colosseum in Rome. These structures are typically designed to be visually striking and can represent the values, beliefs, or achievements of a society. Many monumental structures are built to commemorate important events or figures, such as the Lincoln Memorial in the United States, which honors President Abraham Lincoln. They often attract tourists and serve as important sites for education and reflection, showcasing the artistic and engineering capabilities of their time.
