History
The Horologium Augusti or Solarium Augusti was an ancient monument of the Campus Martius built during the reign of Augustus. In theory, it functioned as a giant solar marker. An obelisk relocated to Rome from Heliopolis served as the gnomon. The obelisk today stands in the Piazza di Monte Citorio.
