Statement of Significance

Description of Historic Place

Cathédrale Notre-Dame de l’Assomption is located on the corner of St George and Lutz Streets in Moncton. It consists of a grey sandstone cruciform Gothic Revival cathedral structure with a prominent square bell tower, built between 1939 and 1940.

Heritage Value

Cathédrale Notre-Dame de l’Assomption is designated a Local Historic Place because it is a good example of the religious Gothic Revival architectural style. It is also recognized for its religious importance for the Acadians living in the Moncton region.

Cathédrale Notre-Dame de l’Assomption was built between 1939 and 1940 by Ambrose Wheeler Limited. The architectural plans were designed by Louis-N. Audet of Sherbrooke, Quebec. It is known across Canada for its blend of classic Gothic Revival features, such as its cruciform footprint, Gothic arch windows, sandstone masonry and traditional ecclesiastic décor with more modern elements. It is the largest religious structure in the Moncton’s skyline.

In 1955, in preparation of the Bicentennial of the Acadian Deportation, many improvements to the interior were made, including the installation of a Casavant Brothers pipe organ, permanent church pews and 10 stained glass windows by Auguste Labouret of France depicting women from the bible. Other renovations saw remains of several Monsignors removed from the original crypt and placed within a chapel and alcoves on the main floor.

Cathédrale Notre-Dame de l’Assomption is also designated for its religious importance for the Acadians living in Moncton. In 1936, Pope Pius XI created the Archdiocese of Moncton. The crypt and unfinished chapel of Notre-Dame de l’Assomption, established in 1914 by Msgr. Henri-D. Cormier at the corner of Lutz Street and St. George Street, was chosen as the proper location for the new cathedral. Opening services were conducted by Cardinal Msgr. Jean-Marie Rodrigue Villeneuve, Archbishop of Quebec and Louis-Joseph Arthur Melanson, Archbishop of Moncton. Celebrations and commemorations of significant events within the Acadian community are honoured in statues, monolithic inscription stones, stained glass windows and other decorative details.

Besides being religiously and culturally significant, many of the interior adornments stand alone as significant artistic achievements by local Acadian artists and artisans. During Pope John Paul II’s visit to Moncton in 1984, the Cathédrale Notre-Dame de l’Assomption was the pontiff’s only major stop besides the specially constructed Papal Visit site.
