Introduction to Aqua Alexandrina and Its Historical Significance

Nestled in the eastern outskirts of Rome, the Aqua Alexandrina stands as one of the final monumental achievements of ancient Roman engineering. Commissioned by Emperor Alexander Severus in 226 CE, this aqueduct was primarily built to supply water to the lavish Baths of Alexander in the Campus Martius. Its construction marks the culmination of more than five centuries of Roman aqueduct innovation (Turismo Roma; Roman History). Stretching over 22 kilometers, the Aqua Alexandrina is renowned for its innovative use of brickwork and its towering arches, some exceeding 20 meters in height. Remnants of these majestic structures are still visible today in districts like Centocelle and Tor Pignattara (LA Daily Gazette; The Archaeologist).

Unlike Rome’s more crowded attractions, the Aqua Alexandrina offers a unique, open-access experience where ancient ruins blend harmoniously with modern urban life and tranquil green spaces. This guide provides essential information on visiting hours, ticketing (the outdoor remains are free to access), transportation, and practical tips, as well as a detailed look at the aqueduct’s historical context, engineering marvels, and enduring significance as a symbol of imperial power and civic pride (Rome Tourism; Evendo).

Whether you’d like to stroll beneath the monumental arches at Viale dell’Acquedotto Alessandrino, capture stunning photographs at golden hour, or combine your visit with nearby sites such as the Baths of Caracalla or Parco degli Acquedotti, this guide equips you with everything needed for an enriching and memorable experience (The Wanders; Trip.com).

Origins and Construction

The Aqua Alexandrina was the last of Rome’s eleven major aqueducts, commissioned by Emperor Alexander Severus in 226 CE to supply water to the newly built Thermae Alexandrinae (Baths of Alexander) in the Campus Martius (Turismo Roma; Roman History; LA Daily Gazette). The aqueduct sourced its water from springs in Pantano dei Grifi (now Pantano Borghese), about 22–24 kilometers east of Rome, near the ancient town of Gabii (Romanaqueducts.info).

Engineering Features and Route

Spanning approximately 22.4 kilometers, the first 6.4 kilometers of the Aqua Alexandrina ran underground to protect the water supply and maintain a gentle gradient. After this, the aqueduct emerged above ground, traversing valleys and ridges on a series of arches and bridges, with some arches in the Centocelle area reaching heights of over 20 meters (Learning History; LA Daily Gazette). The aqueduct’s distinctive use of brick lining instead of the earlier tuff blocks signals advances in Roman construction techniques during the third century CE. As Aqua Alexandrina neared Rome, it descended and became an underground canal, likely entering through Porta Prenestina (modern Porta Maggiore), supplying water to the Esquiline and Quirinal hills and the Campus Martius (LA Daily Gazette).

Historical Context and Urban Impact

Constructed during a period of imperial instability, the Aqua Alexandrina’s completion highlights the enduring importance of public works in Roman policy (Popular Archaeology). At its peak, Rome’s aqueduct network delivered vast quantities of water to sustain the city’s population, support public baths and fountains, and ensure sanitation (Learning History).

Decline and Later History

In 537 CE, during the Ostrogothic siege, Rome’s aqueducts were deliberately cut, leading to the decline of urban life (Popular Archaeology). The Aqua Alexandrina was abandoned for centuries, with only portions remaining above ground, mainly in Rome’s eastern outskirts (LA Daily Gazette). The urban section remains largely undiscovered (LA Daily Gazette).
