Major projects in the french diocese of Meaux

The diocese of Meaux covers the department of Seine-et-Marne, in the Ile-de-France region, the most populous region of France. Close to the capital Paris, the diocese has a history that goes back to the first centuries of Catholicism. Today, the Seine-et-Marne is the largest department in Ile-de-France, and the most visited by tourists after Paris.

The department also has one of the highest demographic growth rates in France. Its population has multiplied by 2.7 since the 1960s to reach 1.4 million inhabitants in 2020 (which is significantly higher than the neighboring departments). The department benefits from a dense and diversified economic network of 84,000 companies

The Saint-Colomban project in Val d'Europe

The project is located in Val d’Europe, an economic and tourist sector of the Seine-et-Marne. Situated in the north of the department, 30km east of Paris, Val d’Europe is a district of Marne-la-Vallée, famous for being home to Euro Disney. Today, this territory, which has experienced one of the strongest demographic and socio-economic dynamics in France in recent years, has a population of 55,000 inhabitants with 37,000 people employed, and should grow to 90,000 inhabitants by 2050. It receives nearly 40 million visitors per year, split between the Disney parks, its shopping malls and leisure and accommodation facilities.

A unique project in France : 

  • Construction of a large-scale church for up to 900 people
  • Opening of a Catholic school under contract with the French State. It will welcome 1500 students from kindergarten to high school
  • Development of a cultural center which includes an auditorium for conferences, concerts, exhibitions… It will be a reminder of the history of Saint Colomban and will be a milestone on the Via Colombani, in connection with the 4 existing cultural centers in France, Ireland and Italy.

This new city could not remain without a church. This project responds to a vital need for a Catholic presence. Along with a large school, it will become a place of transmission and evangelization.

City of Chelles

The Sainte-Bathilde project

Chelles is a Merovingian « capital », associated with the ruling family of the Franks in the 6th and 7th centuries. Clovis, first King of the Franks, stayed in Chelles and his wife Clotilde founded a small church there. Bathilde, a previously enslaved woman who became queen of the Franks by marrying Clovis II, lived in the 7th century. A woman who embodied justice and freedom, she established equal taxation for all, helped large families and prohibited the slave trade. Queen Bathilde founded an abbey in Chelles where she lived out the rest of her life. She was canonized in the 11th century.

Today, Chelles is the second most populated town in Seine-et-Marne with more than 54,000 inhabitants.

The city has deep historic and Catholic roots, but this history is no longer as apparent and needs a soul in its heart and to reconnect with its origins.

The main features of the Saint Bathilde project

  • Construction of a large church-sanctuary dedicated to Saint Bathilde in the new town center square to replace an old chapel that was too small and that was deconsecrated and destroyed in 2021
  • Capacity of 800 seats to welcome the growing number of members of the parish community
  • Adjoining premises: parish rooms, a presbytery for priests and seminarians

Main stages of the Sainte-Bathilde project:

  • June 2019:
    obtaining demolition and building permits
  • June 7th, 2021:
    deconsecrating of the old chapel followed by its destruction parishes
  • October 2021:
    archaeological pre-excavation
  • February 2022:
    approval from the Ministry of Culture to start work
  • January 2023:
    tender for the works
