Historical relics are physical objects from the past that provide insight into previous cultures, societies, and events. These items can include artifacts like tools, pottery, and clothing, as well as structures such as buildings and monuments. They help historians and archaeologists understand how people lived, worked, and interacted in different time periods. Many historical relics are preserved in museums or archaeological sites, where they are studied and displayed for public education. Notable examples include the Rosetta Stone, which helped decode ancient Egyptian writing, and the Terracotta Army, a collection of sculptures that represent the armies of Qin Shi Huang, the first Emperor of China.
