December 8, 1850
The Cathedral of the Immaculate Conception was dedicated in Mobile after nearly 15 years of construction. Built in the Roman style, the impressive structure included a brick foundation with 10-foot-thick walls and two rows of Doric columns separating the interior into three naves, each with barrel-vaulted ceilings. In 1962, the cathedral was designated by Pope John XXIII as a Minor Basilica – an award given to churches because of their historical, cultural or artistic significance as a place of worship – and, in 1971, was placed on the National Register of Historic Places as a contributing property to the Church Street East Historic District.
