The Stepped Stone Structure is the name given to the remains at an archaeological site (sometimes termed Area G) on the eastern side of the City of David. It is a curved, high, narrow stone structure which is built as a series of terraces (hence the name). It was uncovered during a series of excavations by R.A.S. Macalister in the 1920s, Kathleen Kenyon in the 1960s, and in the 1970s-1980s. Kathleen Kenyon dated the structure to the start of Iron Age II (1000-900 BC); Macalister believed it to be Jebusite in origin, therefore from the Bronze Age. Macalister, the first to excavate the structure, called the remains he had found a "ramp"; other scholars, after the more recent discoveries by Kenyon and Shiloh, have suggested that it might be a retaining wall, or a fortress.
