What Roman column in Rome commemorates Emperor Marcus Aurelius's military campaigns?

The Roman column in Rome that commemorates Emperor Marcus Aurelius’s military campaigns is the Column of Marcus Aurelius.

This victory monument stands in Piazza Colonna, in the northern Campus Martius. Its spiral relief records Rome’s wars against Germanic and Sarmatian peoples during the emperor’s reign, especially the Marcomannic Wars along the Danube. Construction probably began after Marcus Aurelius died in 180 AD and was completed around 193, under Emperor Septimius Severus.

The column was modeled on Trajan’s Column, a frequent source of confusion. Trajan’s monument celebrates the emperor’s Dacian Wars, while Marcus Aurelius’s column focuses on later conflicts. The relief rises in a spiral approximately 112 meters long and winds upward 21 times.

The shaft is about 29.6 meters high and is made from roughly 27 or 28 blocks of Carrara marble. An internal staircase contains around 190–200 steps. A statue of Marcus Aurelius originally crowned the column, but Pope Sixtus V replaced it with a statue of Saint Paul in the sixteenth century.
