The earth pyramids of Ritten (German: Erdpyramiden am Ritten; Italian: Piramidi di terra del Renon [piˈraːmidi di ˈtɛrra del reˈnon]) are a natural monument that is located on the Ritten, a plateau not far from Bolzano in northern Italy. Earth pyramids are a fairly widespread phenomenon that exist in various locations, such as South Tyrol and Platten.

The original name in this area for these earth pyramids is Lahntürme, i.e., landslide towers.^[1] They originate from glacial moraine rocks. The columns of the pyramids may be more or less elongated, and the higher they are, the thinner they get, ending usually with a stone cover. These earth pyramids are constantly evolving, continuously eroding, and will possibly collapse and make way for new formations.
