This PWA-funded courthouse, constructed when the parish seat was transferred from St. Bernard to Chalmette, is an austere Moderne structure, with a central section four stories in height and wider than the slightly recessed three-story wings. Faced with smooth limestone and sparely ornamented, the reinforced-concrete structure projects an image of weight and serious purpose—characteristics of Weiss, Dreyfous and Seiferth’s designs. Narrow foliate-patterned carved bands placed to define architectural parts enhance the building’s linear qualities. Occupying the full width of the interior central section is a two-story lobby with curved staircases at each end leading to a balcony, a geometrically patterned terrazzo floor, and walls sheathed in gray-veined marble. The principal courtroom has wood paneling and narrow vertical windows with metal mullions on the exterior that are decorated with stylized female representations of Justice, alternating with magnolia flowers. The courthouse was flooded by seven feet of water from Hurricane Katrina but was restored and reopened in 2013.
