Origin and history

The church of Saint-Jacques de Montgeron, located in Essonne, replaces a 12th-century medieval building deemed old in the mid-19th century. Its construction (1855-1856) is part of a global urban project, including town hall and school, on a land offered by the local owner Baron Rottembourg. The architect Louis Julien Laroche designs a neo-Roman building with a basilical plan, with a nave with seven spans and a three-sided apse, supplemented by side chapels. The building was consecrated on 13 October 1856.

The stained glass windows, made in 1940-1941 by the Mauméjean workshops (directed by Charles Mauméjean in Paris), form a coherent set of 40 glass windows, mosaics and wall paintings. Their figurative style includes biblical scenes such as St James's Takeoff – where a local rumor evokes a resemblance of the executioner to Hitler – or tributes to the French shrines (Lourdes, Paray-le-Monial). Innovative techniques, combining blown glass, cabochons and slabs, create relief effects inspired by merovingian goldsmiths.

Ranked a historic monument in January 2021, the church illustrates the architectural and artistic evolution of Montgeron, from its reconstruction in the 19th century to its enrichment by a modern sacred decor. The initial project, led by parish priest Pierre Le Couëdic, aimed at a "total work" integrating architecture, furniture and decorative arts, in a dialogue between tradition and modernity. The building remains a testimony of the local patronage (family of Rottembourg) and the influence of Mauméjean workshops in Île-de-France.
