The Drususstein ("Drusus stone") is a nearly 20-metre-high masonry block of Roman origin in the grounds of the citadel of Mainz, Germany. It was originally cased in marble. Researchers now largely accept that it is a remnant of the cenotaph mentioned by writers such as Eutropius and Suetonius, erected in 9 BC by Roman troops in honour of the deceased general Drusus, in Mogontiacum (now Mainz).
