A market place or trading centre, particularly of an ancient city.
2007, John Darwin, After Tamerlane, Penguin 2008, p. 28:
Only where churchmen congregated or rulers established their emporia—licensed depots for the long-distance trade in luxuries—did any vestiges of urban life survive.
A shop that offers a wide variety of goods, often used facetiously.
With a name like "The Wine and Spirits Emporium", no wonder the prices are so high.
