Rome’s Horrea Piperataria – or ‘Pepper Warehouse’ – receives little more than a passing mention in our discussions of the Imperial Forum. Given the minimal archaeological and textual record, this is not surprising. Within a century of its Domitianic construction, the horrea had all but burned to the ground. When the Basilica of Maxentius was constructed in the early fourth century, the horrea disappeared from view entirely. It would seem that Rome’s emporium of herbs and spices from across the Empire has little to tell us. But is that the whole story? Recent excavations beneath the Basilica have uncovered new details about the warehouse’s internal space. If we consider the visual literacy of Rome’s population, we can situate the horrea within an architectural typology and begin to uncover its presence within the city. And adopting a post-colonial lens both reconstructs the social experience of this site and interrogates its post-classical scholarly reception. Many locations across the Roman world possess an equally fragmentary record. Yet many also enjoy considerably more attention in the literature than the Horrea Piperataria. This paper will reveal the horrea as a site of multicultural exchange and social identity in a diverse ancient city. In this process, it will also question whether eurocentrism incorrectly shaped – or rather diminished – our view of the Horrea Piperataria as being of minimal importance in the imperial power landscape.
