Núcleo Arqueológico da Rua dos Correeiros (Fundação Millennium bcp)

This guide to the Núcleo Arqueológico da Rua dos Correeiros in Lisbon starts in 1989, when workers digging a car park beneath the building struck something undisturbed for two thousand years: a Roman fish-processing factory from Felicitas Julia Olisipo, ancient Lisbon. It follows the bank that owned the site as it halted construction and called in archaeologists, who spent years excavating layer after layer of the city's history stacked one civilization on top of another. Listen for how the tanks once turned local mackerel into a fish sauce prized across the Roman world.
