This paper offers a fresh look at the two Hellenistic granaries from Morgantina, situating them within their local urban setting and within the socio-political landscape of Sicily in the 3rd and 2nd centuries BCE. First, I argue that when constructed the granaries served as centralized points for the collection, storage, and redistribution of the agricultural tithe collected during the reign of the Syracusan monarch, Hieron II (r. 269-215 BCE). As documents of Hieronian administration, these monuments speak to the impact that royal authority had in shaping the built environment of the Hellenistic city. Second, I discuss the abandonment of the East Granary and its repurposing as a pottery workshop against the backdrop of wider political and social changes occurring at Morgantina and across Sicily during the century that followed Roman conquest of the island. Throughout the paper, I make reference to new archaeological material recovered in the course of excavations inside the two granaries during the 2011 and 2013 campaigns of the American Excavations at Morgantina.
