[1][2] The building was originally called the CM Tower, for Calcasieu Marine National Bank, then renamed the Hibernia tower after Hibernia National Bank purchased Calcasieu Marine.

Badly damaged by Hurricane Laura in August 2020, the tower stood empty until it was demolished in September 2024.

In 2007, the facility underwent major repairs and security upgrades such as the addition of ballistic protection to the exterior glass.

The reconstruction of the lower floors and the renovations of the atrium, tower facade, and major tenant spaces were designed and project-managed by Vincent-Shows Architects of Sulphur.

[3] The tower was left vacant and in 2023, the city gave Hertz Investment Group, who had acquired the building in June 2007, a deadline of November 2024 to either repair or demolish it.

[5] Hertz reached a settlement with their insurers and offered the building for sale, but it did not find a buyer.
