National landmarks are significant sites recognized for their historical, cultural, or architectural importance. These locations can include buildings, monuments, parks, and other structures that represent the heritage of a nation. In the United States, for example, landmarks like the Statue of Liberty and Mount Rushmore are celebrated for their unique contributions to the country's identity. Preserving national landmarks helps educate the public about history and culture. They often attract tourists and serve as symbols of national pride. Many landmarks are protected by laws to ensure their maintenance and conservation for future generations, allowing people to connect with their past.
