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). During the early days of the Principate, the Drususstein was the starting point for elaborate memorial services in honour of Drusus, and the centre of the imperial cult in Mogontiacum. A procession road linked it to the theatre of Mogontiacum, which contained approximately 12,000 seats, making it the largest known theatre north of the Alps. It may have hosted a part of the annual ceremonies at the day of Drusus' death, and probably also at his birthday. After being robbed of its marble casing in the early Middle Ages, the Drususstein served as a watchtower in the fortifications of the city in the 16th century. For that purpose a staircase and doorframe were made in the structure, which had been up to that point a solid building.
