This is a list of ancient monoliths found in all types of Greek and Roman buildings. It contains monoliths * quarried, but not moved * quarried and moved * quarried, moved and lifted clear off the ground into their position (architraves etc.) * quarried, moved and erected in an upright position (columns etc.) Transporting was done by land or water (or a combination of both), in the later case often by special-built ships such as obelisk carriers. For lifting operations, ancient cranes were employed since ca. 515 BC, such as in the construction of Trajan's Column.
