Along the side of the Bouleuterion, from south to north, runs the Via Sacra , or Sacred Way, the "cardo maximus" road used for religious procession that was rediscovered in 1907. Long about 9 kilometers, the Via Sacra, linked the city of Poseidonia-Paestum at the ancient temple of Hera Argiva, built near the river Sele.
The road was paved with large limestone blocks that still show the indentations left by the wagon wheels.
The area east of the Via Sacra made up the northern part of the Greek city’s agora, which was built up into a residential area after the Romans took control of the city and the forum was established further south.
