I’ve always been interested in architectural reassignments such as churches being turned into mosques. Ancient structures were often given new life by modification for new uses; Greco-Roman theaters were modified for less edifying gladiatorial entertainments, as were Greek stadia. This one is a pretty simple one as far as conversions go. This picture shows the old Roman amphitheater of Cartagena, Spain, which was in later centuries revamped into the town’s bull ring. It’s all in ruin now, however, even the more recent parts ready to fall. In this arid part of Spain, not often visited by tourists, there’s not a lot of money for big restoration projects, but the Cartegeneans have done a good job restoring their Roman theater, which has a museum with artifacts from the city’s Roman past.
