Holy Trinity Catholic Church, Catholic church in Shreveport, Louisiana.

Holy Trinity Catholic Church is a Romanesque Revival church built in 1896 in Shreveport, Louisiana. Its interior features a Communion Rail, one of the last fully present in a Catholic church in the city, and two Gothic Revival side altars brought from a former church in the area.

The parish began in 1856 with a first church built under Father Jean Pierre, its founding pastor. The present building, the third on the site, was completed in 1896. It was listed on the National Register of Historic Places in 1984 and became a contributing property of the Shreveport Commercial Historic District when that district's boundaries were extended on April 29, 2015.

Holy Trinity's first pastor, Father Jean Pierre, and his assistant Father Isidore Quemerais both died in 1873 while tending victims of the city's yellow fever epidemic. The parish keeps their deaths as a founding memory, and the church's early history is told through their service rather than through its buildings.

The church sits on Marshall Street and remains open for visitors to explore its historic interior. The communion rail is still in place for those wanting to see how the space was traditionally arranged.

The two Gothic Revival side altars were brought here from a former church elsewhere in the area, so they are not original to the 1896 building. Look for them flanking the sanctuary, where their pointed-arch style contrasts with the Romanesque Revival interior around them.
