What was the first landmark to be made?

The first known landmarks were likely natural formations, such as mountains or rivers, used by ancient humans for navigation. However, one of the earliest man-made landmarks is believed to be the Great Pyramid of Giza, built around 2580–2560 BCE in Egypt. This monumental structure served not only as a tomb for the Pharaoh Khufu but also as a symbol of ancient Egyptian civilization and engineering prowess.
