Porticus Aemilia

Porticus Aemilia is an ancient Roman commercial structure that stretched along the Tiber River with hundreds of pillars arranged in rows that created multiple aisles. The remains visible today show portions of the original walls and demonstrate how carefully the structure was built into the terrain.

The complex was built in the late 300s before Christ and served Rome as a trading facility for hundreds of years. It was later renewed and modified multiple times to meet the demands of the city's growth.

This structure served as a crucial trading hub where merchants gathered to exchange goods brought upriver from across the Mediterranean. The place shaped how Rome's commerce operated and how the city received essential supplies from distant ports.

The remains are located in the Testaccio district and can be reached on foot through several streets, with some sections more visible than others. It helps to move slowly when visiting and pay attention to where ancient foundations start and end, as they are not always clearly marked.

The structure used a sophisticated system of arches and pillars that allowed it to bridge uneven slopes and create a level working surface. This engineering approach was unusual for the time and shows how innovative Roman builders were.
