Preindustrial cities spatially managed unknown foreigners by type.

Evidence

In some cities, visiting foreigners might be required to lodge in quarters specifically reserved for persons of their type. Thus, in tenth and eleventh century Constantinople, Christian pilgrims stayed at the Hospice of Samson, while Russian merchants were shuttled out to “specially reserved houses in the suburb of Saint Mamas” (Runciman, 1952:62). — Lyn H.
