Castra Pretoria: a journey through time between the praetorians and energy innovation

Castra Pretoria, Rome: from 21 AD to the present, a journey through time!

Used as barracks for the Praetorian Guard under Emperor Tiberius, in 1937 the area was given to the City of Rome's electricity company and transformed to meet growing energy demand and technological advances.

Today it houses Areti's primary high-voltage substation and was illuminated by Cefla Engineering, just in time for Republic Day, June 2, 2025.

Our Stefano Valentini, Project Manager in Electricity Networks, in collaboration with Areti, carried out the street lighting project, here are the photos!

Cefla also has long been involved in the implementation and management of electrical grids, and has overseen the construction and securing of several primary substations, including in Rome. Watch the docufilm on another high-voltage primary substation:
