Libreville Notre-Dame-de-l'Assomption Cathedral, Catholic cathedral in central Libreville, Gabon.

The Libreville Notre-Dame-de-l'Assomption Cathedral stands on the site of the former Fort d'Aumale, the first French naval post established in 1843, on a promontory overlooking the boulevard and the Port-Môle roadstead. Built from 1958 under Archbishop Jean-Jérôme Adam, it replaced the 1864 Notre-Dame-des-Neiges church, which was kept standing in front of it. Its roof gave way from the inside during the rains of 27–28 May 2025, and it has since been closed for consolidation and renovation.

The cathedral was officially inaugurated in 1958, marking an important moment in the development of Catholicism in Gabon. Since its establishment, it has remained the primary center for Catholic religious life in the city.

The cathedral is also called Notre-Dame-de-l'Assomption-Sainte-Marie. It replaced the 1864 church Notre-Dame-des-Neiges, the first stone church built south of the Sahara, which Jean-Rémi Bessieux had blessed and which was restored under a new dedication in 2024. The older church stands on the promontory in front of the cathedral.

The cathedral has been closed since the night of 27–28 May 2025, when heavy rain caused the roof to collapse from inside; consolidation and renovation work is under way. In December 2025 the first load-bearing elements of the new roof frame were installed. Check locally before planning a visit, as access is restricted during the works.

The cathedral stands on the site of Fort d'Aumale, the first French Navy colonial post in 1843. Its predecessor, Notre-Dame-des-Neiges, was blessed by Jean-Rémi Bessieux in 1864 and is considered the first stone church built south of the Sahara; it was kept rather than demolished. In May 2025 the roof gave way after heavy rain, and the building closed for consolidation work.
