Some city mottos that use «urbs» in their Latin form, can you recognize them all? :) «Urbs aeterna». «Urbs Primis in Indis». «Urbs in horto». «Urbs Antiqua Fuit Studiisque Asperrima Belli». «Actibus immensis urbs fulget Massiliensis». «Urbs progrediens media in civitate». «Urbs inter agros». «Populus felix in urbe felici».
Also the locution Urbi et orbi. (The Pope makes the benediction to the city, and to the world)
I cheated a bit, because of lot were unknown to me (specially the American ones), so, be careful, spoiler:

Saint Marys, Ohio, is "the city in the fields", Santa Monica, California, is where are the "happy people in an happy city" (shouldn't be "felici" but "felice" by the way, but it's written like this), Campbellsville, Kentucky, is the one with the translation "the city in the middle of the commonwealth".
