Located at the junction of the Mobile River and Mobile Bay on the northern Gulf of Mexico, the city is the only seaport in Alabama.

Mobile was also host to the first formally organized Carnival mystic society, known elsewhere as a krewe, to celebrate with a parade in the United States, beginning in 1830.
