The Cathédrale Notre-Dame de la Treille in Lille stands as a distinct architectural landmark characterized by a construction period that spanned nearly 145 years. The edifice, which blends neo-Gothic religious architecture with contemporary design, was officially completed in 1999.
The history of the cathedral began in 1854 with the laying of its foundation stone. Designed as a neo-Gothic structure, the building’s progress was not linear, as construction was interrupted on several occasions due to a lack of sufficient resources.
A significant turning point in the cathedral’s development occurred in 1947. At that time, Cardinal Liénart decided to invest in the ambitious program to ensure the building’s completion, providing the momentum necessary to move the project forward after decades of intermittent work.
The Contemporary Façade
Despite the renewed efforts following 1947, the cathedral’s façade remained incomplete for several more decades. The work on the front of the building was not finalized until 1995.

The project to complete the façade departed significantly from the original design of the cathedral. This bold modern approach was entrusted to architects Pierre-Louis Carlier and Peter Rice. The resulting structure is noted for bearing no resemblance to the original plans, which contributes to the monument’s unique visual allure.
The modern additions include an immense glass roof that allows light to stream into the interior during the day, creating a reflective environment that contrasts with the traditional neo-Gothic elements of the building.
Artistic Contributions
The completion of the cathedral involved several prominent artists who contributed specific elements to the exterior and interior. The cathedral’s rose window was designed by artist Ladislas Kijno, while the portal was created by sculptor Georges Jeanclos.
These artistic contributions, combined with the height and decor of the interior, define the eclectic nature of the building. The cathedral is located in the Vieux-Lille area, where its stained glass windows are featured as part of the district’s cultural and historical heritage.
The 1999 official completion marked the end of a process that began in the mid-19th century, resulting in a structure that serves as a bridge between traditional French religious architecture and modern design.
