Two of six original Doric columns mark the entrance to the ruined Prytaneum (town hall) and city treasury. Here and elsewhere in Ephesus, note the differences between the Ionian Greeks' heavily ornamented, spiralling columns, and their smooth, unadorned Roman counterparts. Both coexist randomly across the site, due to ancient retrofitting and modern relocations. A similar difference is notable in arches: the genius of single-material, harmoniously balanced Ionian Greek arches, and the pragmatic use of mortar cement by the Romans.
