The Statue of Liberty officially became a U.S. historical landmark in 1924. Designated as a national monument, the statue was already a symbol of freedom and democracy upon its dedication in 1886. However, the recognition in 1924 was crucial for its preservation and highlighted its significance in American history. The National Park Service took responsibility for its care, which helped ensure that future generations would appreciate its value as a cultural and national icon. This designation emphasizes the ongoing importance of the Statue of Liberty in commemorating the ideals of liberty and the immigrant experience in the United States.
