Ponte Mammolo, Ancient stone arch bridge on Via Tiburtina, Rome, Italy
Ponte Mammolo is a stone arch bridge spanning the Aniene River in northeastern Rome. The structure features three arches built from tuff and travertine, carrying traffic along Via Tiburtina across the riverbed.
The original Roman structure was replaced in 1871 after sustaining damage during conflicts of that era. The reconstruction followed traditional Roman engineering methods while maintaining its role as a key transport link.
The bridge takes its name from Julia Mamaea, mother of Emperor Alexander Severus, connecting Rome to its eastern territories. Today visitors see how the structure carved from local stone has shaped the relationship between the city and the Aniene River valley.
The best way to view the bridge is from Via Tiburtina, where you can see it from several angles and appreciate its structure. During low water levels, visitors can reach the riverbanks to examine the foundations and visible stonework more closely.
When water levels drop, remnants of the original Roman foundations become visible, showing different construction techniques from various periods. These overlapping layers reveal how engineering methods evolved over centuries of use.
