Where have Ziggurats been found in South America?

Ziggurats, which are step-like structures associated with ancient Mesopotamian cultures, have not been found in South America. However, South America is home to various ancient civilizations that built their own monumental structures, such as the Inca and the Moche, which created impressive pyramidal forms. The closest equivalent in South America might be the stepped pyramids of the Moche culture, like the Huaca del Sol and Huaca de la Luna in Peru. These structures, while similar in form, differ significantly in cultural context and purpose from true ziggurats.
